1. What is the TypeScript programming language?

TypeScript is open-source, object-oriented programming, strongly typed language. The language was developed and maintained by Microsoft in 2012. TypeScript is a compiled or superset of JavaScript language that signifies that every JavaScript project or program can efficiently operate in typeScript.

The leading purpose of the language is to develop JavaScript applications in all the platforms and also serve as both client-side and server-side language. The language also combined fascinating features such as Type, type checking(an amazing feature we will discuss later), and some OOP features that make the language so much popular.

History

TypeScript language was developed by Anders Hejlsberg, lead architect of C# and creator of Delphi and Turbo Pascal. In 2010 he began operating on the language at Microsoft. Finally in 2012 the first version i.e. T.S. .8 was released. But the language encountered a lot of criticism in the world because it does not support major IDE’s apart from Microsoft Visual Studio that is not available for Unix and OS. TypeScript is compiled into JavaScript that makes the code easy to read and debug.

2. The latest version of the TypeScript language.

Let’s discussed the version of TypeScript language. From TypeScript .8 version 2.0, 3.0 to 4.0. Undoubtedly TypeScript developers continuously try to keep the language up-to-date by computing all the essential features which benefit all the developers to get all the advantages of the language. In the year 2021, we are using the TypeScript 4.1.5 version that released on 10 February 2021. TypeScript is open for Windows, Linux, and Docker.

Interesting Facts

  1. TypeScript language is one of the most widespread languages. According to the PYPL Popularity of Programming Language in Feb 2021 TypeScript ranked #10 in all the programming languages that are insane. So now you can predict that the language is grown a lot in some current years.
  2. Angular 2 one of the most popular Frameworks is written in Typescript.
  3. TypeScript compiler i.e. tsc is written in TypeScript language. Firstly it is compiled into plain JavaScript and then it is executed in any JavaScript engine.

3. Features of the language

  1. TypeScript is a concise, easy to learn language that is totally similar to JavaScript. It implies that signifies that every JavaScript project or program can efficiently operate in typeScript. By simply changing the extension .js to .ts .
  2. The language support object-oriented programming features such as classes, interfaces, encapsulation, abstraction, polymorphism, etc. these features benefit all the programmer to write code easily, readable, easy to find bugs, and they can comfortably maintain the code.
  3. The most valuable innovation that is added to the language is it uses strongly-typed or supports static typing. With the help of static typing, we can easily find errors or bugs in the code at the time of compilation. Without running your code every time we can easily find errors. JavaScript is lagging from this feature.
  4. TypeScript approves ECMAScript 5 and ECMA Script 6 specifications. Along with this it also added some more features such as interfaces, generics, classes, type annotations, etc.
  5. The language operates amazingly with other frameworks such as Angular, Vue, React, etc. Angular 2 one of the most popular Frameworks is written in Typescript. That’s why the language gained so much popularity. It also supports popular libraries such as react intl, components, formik, etc. Some libraries of JavaScript are written in TypeScript such as Rx.js, Svelte, Angular, etc.
  6. TypeScriptis platform Independent language. It runs on every platform where JavaScript runs.

Now let’s talk about the advantages and disadvantages of TypeScript

Advantages:-

  1. TypeScript lookout for all the errors or bugs from the code at the time of compilation.
  2. The language provides you static typing.
  3. TypeScript supports ES5, ES6, and additional features.
  4. It runs on every browser or JavaScript generator.
  5. TypeScript operates the interface, modules, and many more.

Disadvantages:-

  1. TypeScript takes time to compiles the code.
  2. It does not provides classes concepts.

4.Why you have to learn the TypeScript language?

Now, most people having a question that why I have to invest time in learning the TypeScript language, Why TypeScript? why not JavaScript? What Developers or programmers have opinions on TypeScript? .

 So let’s clear all the points. TypeScript is open-source, object-oriented programming, strongly typed language. The language was developed and maintained by Microsoft. As we all know that TypeScript is comparable to JavaScript language. But TypeScript language extends more innumerable specialties than JavaScript such as Static typing, Interfaces, Modules, Generics, Types, supports ES6 features, and many more.

According to the PYPL Popularity of Programming Language in Feb 2021 TypeScript ranked #12 in all the programming languages that are insane.

Now lets us see why Programmers have to spend their time learning TypeScript, not in JavaScript?

JavaScript is a client-side language and scripting language, a cross-platform that is essentially designed for creating dynamic websites or web pages alive. But JavaScript is lagging from some fantastic features that TypeScript introduced. J.S. does not provide you. As we all know that TypeScript is a superset of JavaScript and the language also added some additional features. If JavaScript does not update their language in a few years by adding those fantastic features then TypeScript definitely will be the first priority(it still has) for every developer to develop their applications.

Now let us see why companies are using TypeScript language

Most of the companies are using TypeScript language because we have to think about the future challenges that the language has to face. As we all know that JavaScript is lagging from some amazing features. So why not use TypeScript. If TypeScript language provides you all the features of JavaScript language and also those additional features then surely it should be the first preference. If we talk about those amazing features such as static typing. Static typing helps to tackle all the errors or bugs at the compilation time. Whereas in JavaScript you will not find any errors unless your will run. These features help to improve the efficiency of the code and take less time to develop any applications.

Now let’s talk what are the features from which JavaScript is lagging and TypeScript has?
  1. TypeScript is object-oriented programming whereas J.S. is a scripting language.
  2. It provides you strongly-typed or supports static typing whereas J.S. does not provide you.
  3. TypeScript code should be compiled first whereas JavaScript does not compile.
  4. T.S. uses concepts like generics, interfaces, modules, etc whereas J.S. does not have such concepts.
  5. It supports optional parameters whereas J.S. does not provide you this feature.
  6. TypeScript supports prototyping whereas JavaScript not.

What Developers or programmers have opinions on typeScript?

“We choose TypeScript for various purposes. With TypeScript, most of our team posts are said things like ‘I now really understand most maximum of our personal code!’ because they can simply cross it and experience connections much strong. And we’ve obtained numerous faults via TypeScript’s checks.” — Brad Green, Engineering Director – Angular
