So, let us start!

What is TypeScript?

With programming languages, fun becomes as they advance.

When you started to believe that Java Script had it all, TypeScript superseded it.

TypeScript has everything that JavaScript has and more.

Developed and managed by Microsoft, TypeScript has two distinct advantages over JavaScript. 

The first is that it acts as a transpiler to make the advanced features of ECMAScript available to all web browsers using a polyfill, which was previously impossible.

With TypeScript, you have a strongly-typed code ready at design time that is free of any "type"

Secondly, it allows the software to utilize static typing and catch potential issues early in the development lifecycle. 

This helps to reduce the unit’s test time and efficiently increases the program’s run time. 

In simpler words, with TypeScript, you have a strongly-typed code ready at design time that is free of any “type.” 

TypeScript erases the interfaces, types, aliases, or pseudonyms at transpilation and simultaneously creates a common file with JavaScript with better compiler options. 

So yes, TypeScript is simply a superset of JavaScript that contains a syntax for types.

It provides more efficient tooling without additional code at every scale and runs everywhere – on the web browser or your apps.

Benefits of Using TypeScript

There is always a reason to learn a new skill or programming language, and here is why you must learn to use TypeScript:

You Can Create ECMAScript by leveraging TypeScript

Enables you to use better tooling to generate codes that work on old apps or browsers, using specific versions of JavaScript.

Static Typing with TypeScript

Allows you to imply better programming languages and create object-oriented codes.

Static Typing is one of the benefits of using TypeScript

It also enables easy code for the refractor.

TypeScript Supports Diverse Software and Documents

Including API documentation, React, NodeJS, JS library, BootScrapJS, and others.

TypeScript Supports and Makes it Easy to Use Multiple Frameworks

Such as Angular, Vine, and React.

NPM is a Part of TypeScript

It allows you to acquire access to innumerable resourceful libraries, which also makes it easy for you to learn TypeScript.

TypeScript Compiler Warns You About Any Errors

Such as if you attach a numeric value to a string value at compile time.

Easy Maintenance

TypeScript makes it easy to read, access, and check the types and other things in your code.

TypeScript Contains Several Amazing OOP Features

Including Inheritance, Modules, and Classes that take the application development game to the next level. 

Types of TypeScript

Before we tell you about the various resources that can make you a TypeScript pro, it is essential to learn about the different types. 

How To Learn TypeScript - TypeScript has eight principal types, including Number and String

If you are familiar with JavaScript, you would know it has eight principal types, including:

  • Number
  • String
  • Null
  • Undefined
  • Object
  • Symbol
  • Bigint
  • Boolean

However, all of these are “dynamic” types, and TypeScript comes with an additional set of “static” types, such as:

  • Assigning types
  • Array
  • Void
  • Enum
  • Tuple

All of these types in TypeScript are divided into three categories:

  1. Any it simply means a “variable of any and every type,” as it contains all data types in TypeScript
  2. Built-in – it uses specific data types such as string, number, boolean, null, void, and undefined
  3. User-defined – it includes an interface, array, enum, tuple, and class
