What is Typescript?

Now, what can be your answer when asked about what a Typescript is? You might give it a better approach or perhaps get confused on how to answer it. 

Typescript is a programming language that is evolved and nourished by the Microsoft agency. It is a JavaScript superset and hence contains all the JavaScript constituents. In other words, Typescript is a language made for extensive JavaScript expansion.

These expansions can be executed on the entire existing browser, host or any Operating system. Furthermore, Typescript is a Microsoft language and as well a combination of tools.

As you may know, Typescript is unable to run on the browser directly. This implies that it requires a compiler that will compile the Typescript files and come up with them in a JavaScript file. The JavaScript file compiled can therefore go directly on the browser.

Typescript brings in, voluntary types, modules and classes to JavaScript. Among all the other features of Typescript, the well-known Angular Framework has been rebuilt in Typescript. Typescript allows JavaScript developers to employ better productivity tools, practices like code refactoring and static checking when expanding JavaScript applications.

Typescript is voluntary; it has Typescript inference that permits a small type annotation to enhance a significant change to static confirmation of your code. Typescript, just as other Microsoft Languages, allows you to describe interfaces in the middle of software constituents and procure an insight into the conduct of present JavaScript Libraries

Typescript provides the necessary assistance for the most recent and the most evolving JavaScript characteristics. These features include these from the ECMAScript 2015 and the upcoming proposals, which include: sync and decorators. They all contribute to coming up with a more complex constituent.

Is Typescript a framework?

Well, you must have been wondering whether Typescript is a framework or perhaps something of that sort! Before we get deep into that, let’s first define what a framework is and its relation to JavaScript.

From the general knowledge of programming languages, a framework is a theoretical way whereby software issuing out additional functions can be changed selectively by bringing in more written codes for users. A framework provides a more developed way of generating applications.

Having that in mind, it is as well better to get into the knowledge of the key features that separate the framework from the normal libraries.

Below are the features:

• It has an inversion of control
• The default behaviour
• It is extensible
• It has a non-modifiable framework

Now let us dwell on the major topic of Typescript being a framework.

We are all aware of how NodeJS and the JavaScript frameworks are gaining fame day by day. What then should come into our mind is whether we have a Typescript framework or not. 

Five Typescript frameworks are gaining popularity day in day out. I will give a list of Top five Typescript frameworks based on popularity and the number of users.

1. NetsJs
2. FeatherJS
3. LoopbackJs
4. AdonisJS
5. Ts Ed

Now let’s briefly define what these top five Typescript frameworks mean.

To begin with, NetsJs is the most known Typescript Framework Today. This is because of its Angular system. It was introduced in 2018, and since then, it has grown rapidly and even overcome lots of some js frameworks.

Feathers JS is ranked second after Netsjs. It is worth noting that it supports Typescript in the first-class citizen.AdonisJS is majorly focused on the developers’ ergonomics, speed, and level of stability.

What frameworks use Typescript?

There are several frameworks that use Typescript. To begin with, let’s have a look at NestJS Framework. This is the most known and the commonly used Typescript framework. It’s ranked best today. What comes to your mind? 

NestJS is ranked the best because of its module, which is Angular and this is what inspires it. NestJS is considered one of the rapidly growing frameworks in the NodeJS environs. This seems great!

The most fascinating point is that it has overcome many other Node.js frameworks not only for the Kora and Express. This seems to be a great success in comparison to the years back in 2018 that it was introduced.

Today NestJS has achieved more than 33.9k Github stars. In addition to this, it has more than 54.9k Github Usage in comparison to the designated time of writing.

Its number of downloads is the highest among all the Framework Typescript.

Above are the features and the success of NestJS. So, from what we have discussed, what can be your definition of NestJS? Or perhaps what can you call it according to your understanding. Let’s have a look>

NestJS is a continuous Node.js framework that is used in building quality and scalable node.js website.

Let’s now have a look at the second Typescript framework:

Feathers are ranked the second-best Typescript framework. According to the recent research on the statistics, it recorded about 40.9k downloads weekly. The most fascinating point is that it supports Typescript based on being a first-class citizen. It does this with about 90.5%.

The LoopbackcjSFramework is considered a highly extensive Typescript framework. It’s majorly best for building microservices. In the recent, it was fully upgraded to Typescript in its 4th version of the framework.

It is worth noting that, despite the loopback, 4being ranked the third, it has achieved 3.4k Github Starts. In addition to this, it has about 3.4k usage in Github.

Can you use Typescript with JavaScript?

Questions have emerged about this. Many give it diverse points of view. Before we go deep into this, let’s clear the air with the kind of relation between Typescript and JavaScript.

How does Typescript relate to JavaScript?

In simple terms, Typescript is JavaScript that has types and has acquired the important adoption within the society. According to the developer survey by Stack Overflow, Typescript is ranked top 2 as the most loved Microsoft language.

Now let’s check the relation between Typescript and JavaScript and how you can use Typescript with JavaScript.

In the case of a large JavaScript project, using Typescript will bring you more effective software that is more compatible with the common JavaScript application. It is that simple; the key thing is that Typescript issues voluntary static typing and interfaces.

Typescript is a superset of JavaScript that compiles into plain JavaScript. Typescript brings involuntary types, modules and classes to JavaScript.

What is Typescript used for?

Having mentioned Typescript as a superset of JavaScript language, we are now going to be very simple and brief to the point of what Typescript is used for. What do you think?

Typescript is used to find mistakes prier through a type system. This will make the development of JavaScript more efficient and helpful. 

Typescript can as well perform practices such as static checking. Keep in mind that Typescript enhances the easy reading of the codes and understanding them as well. JavaScript development is entirely based on the Typescript; hence with Typescript, we are in a position to come up with bigger and better improvements over JavaScript.

As you may know, Typescript is as well used to curtail the painful bugs that JavaScript developers go through when writing JavaScript. Typescript is JavaScript with more features included.

Our main focus is on the uses of Typescript and anything else that goes around that. It’s better if you know that Typescript codes are compiled to issue support to the browser. Again, Typescript aligns itself with ECMAScript.This alignment enhances great compatibility.

Consequently, Typescript is used to carefully bring into account all the language features and their functions. It is improving the outcome of the tool in a productive manner. Typescript assists us in re-using the developers’ knowledge by giving similar experiences to developers. This results in a huge improvement over JavaScript.

Typescript has helped many people to understand most of their codes. This is so because; they get in a position to easily transverse the codes better and understand their relationship. Another key use of Typescript is that it simplifies the codes in JavaScript by making it reader-friendly. This brings in another feature of Typescript as being open source.

Typescript example

Are you in the apposition of even mentioning any Typescript example? If you are unable, then you are in good luck. But before we get deep into that, it is good to know that, Typescript examples are classified according to the different types of Typescript. Some of these types include:

1. Static types
2. Generics
3. Decorators

It is from the above-mentioned types that we are going to come up with Typescript examples under each type.

Let’s begin with static types:

In static types, it is further subdivided into two sub-categories. These are then re-built in static type and the user-defined static types. In build, in Types, we find that the Typescript has five builds in types of data. 

To begin with,

Number: Examples:

1. Give 1st: number=12.0

2. Give 2nd: number=0x37CF

3. Give 3rd:number0o377

4. Let fourth: number = 0b111001;  

5. Console.log (first); // 123  

6. Console.log (second); // 14287  

7. Console.log (third); // 255  

8. Console.log (fourth);      

2. String

1. In this case let the identifier be; string=” “; or = ‘ ‘;

Examples:

1. Let employer name (string) be “Rahim”

2. Let employer department: string =”IT”;  

3. Before –ES6, Let the 1st output: string be the employee name +” work in progress” +” employee department” +” department”

4. After –ES6, let output2: string = `${empName} works in the ${empDept} department.`;  

console.log (output1);//Rahim works in the IT department.  

console.log (output2);//Rahim works in the IT department.  

1. . Boolean.

Unlike string and numeric data types, the Boolean can only have 2 values that are True or false

.

Let the identifier: Boolean = Boolean value;  

Examples

Let is done: Boolean= false;  

3. Void.

A void does not return any type of value. Basically, it is usually used when there is no any data type.

Let the un-usable void =undefined

 Example

1. function helloUser(): void { alert(“This is a welcome message”);  

1. let tempNumber: void = undefined;  
2. tempNum = null; tempNum = 123;    
3. Null

Remember null do stands for variables with u ndefined values.

EXamleple

1. Let the number: : number = null
2. Let bool{: boolean = null
3. let str: string = null

The above-given examples are according to the different types of Typescript that we have mentioned there earlier. It is good to note that there are some more examples of Typescript depending on different types like the user-defined we mentioned earlier.

Typescript Tutorial

Are you interested in learning more about Typescript? Before you commence your study, you need to remind yourself of things such as; Typescript is a programming language that is a superset of JavaScript. 

Another thing that you must remind yourself is that Typescript is developed and updated, and maintained by Microsoft. It is worth noting that, Typescript is not directly run on the browser. It requires a compiler to compile and come up with it in a JavaScript file.

This tutorial contains all the necessary topics which are important in learning Typescript.

• Introduction of Typescript.
• Typescript features

• Ambient .etc.

When you get in to learn the course, the first topic that you’ll need to tackle is the Introduction to Typescript. In this topic, the basic info that you’ll need to know is the meaning of Typescript. 

That is, what is Typescript? I hope you are in the position to answer that. In addition to that, another key topic that you’ll need to cover is the Typescript features. They are quite a number, but just to mention a few:

We have:

1. It navigates the codes and prevents bugs
2. It supports ES6
3. It supports classes, subclasses, interfaces and sub interfaces.
4. It offers a fantastic productivity level to Microsoft developers

The next topic that you will find interesting during the course is the Components of Typescript. Here you will get to know what Typescript is made of and how the contents in the study stand in for each other.

Just to bring in a few components: We have

1. The language
2. Typescript compiler
3. Typescript language Services.

Do you find the course interesting with the knowledge of those highlights? 

In that guided sequence, you’ll go through Typescript variables, Typescript languages, how Typescript does its decision making.

Conclusion

 From this article, you need to know that, Typescript is a superset of JavaScript that is developed, maintained, and updated by The Microsoft Company. 

It’s also interesting to have in mind that, Typescript will not bring to an end all the problems in JavaScript at once. It will give you an easy time as a developer and make your work much more enjoyable. It will do this by definitely issuing you with the best information at the best time.

This improvement may seem to be very tiny to you, especially when you are developing low-scale projects or perhaps when you are coding down simple animations. Typescript allows you to give all your attention to the real business idea logic instead of devoting your time to recall all the class information you probably wrote long ago.

This improvement may seem to be very tiny to you, especially when you are developing low-scale projects or perhaps when you are coding down simple animations. Typescript allows you to put all your focus on the real business idea logic instead of devoting your time to recall all the class information you probably wrote long ago.

Why would I advise you to go for Typescript? It is because of its adorable feature that is:

It is easy to maintain. In programming, one of the problems developers experience is the maintainability of the software. Who would leave easy maintainability software for another? The Typescript codes are easy to navigate. In addition to this, it prevents developers from experiencing several bugs during the developing process. 

Remember, Typescript supports classes, subclasses, interfaces and sub interfaces. In addition, it is also compatible with ES6.

Regardless of your choice, remember that,

In case you are an experienced developer, and it occurs that you are working on a relatively tiny coding propjet, JavaScript would be most preferable. But in case you have enough knowledge and more experts, then Typescript will carry the day.

Typescript realizes its goals by providing the necessary support to the already existing JavaScript features. It’s an advanced kind of system that has more preferable options.

Having read through this article, you might be convinced to go for Typescript due to its adorable features depending on the type of your project. Best of luck!
