How programming is better with TypeScript ?

Posted on

TypeScript is a typed superset of JavaScript by definition. As a result, all current JavaScript is TypeScript compliant. Also, you may transform an existing JavaScript project to include type definitions and other language qualities that make long-term project upkeep and scaling much effective and simpler.

TypeScript includes a compiler that converts a .ts file (which cannot be viewed in a browser) to a .js file (which is vanilla JavaScript), as if we had written the entire project in JavaScript. It is quite useful to include this layer of ‘convenience’ above JavaScript code.

There has been a lot of comparison between TypeScript & JavaScript & also a lot of confusion as to which one to learn. However, in this article we will talk about TypeSCript & why it is loved by the programmers.

Key Concepts in TypeScript

There are three things that make Typescript so useful:

  1. Types
  2. Interfaces
  3. Classes and OOP

As a JavaScript developer, TypeScript will help you to:

  • boosting your confidence
  • catching errors before they reach production
  • making it possible to refactor code
  • saving you time from writing tests
  • giving you a good coding experience

When working with new codebases and in larger teams, TypeScript will give you more confidence. You will be less concerned if you are familiar with TypeScript and join a new team or project that uses it. You can count on TypeScript to help you out. Because you can look at something and quickly infer how it works, the language improves code readability and predictability. The type system is to blame for this.

Because TypeScript will detect errors for you, refactoring code becomes easy. When you rename a function, it will warn you if you fail to use the new name someplace else. TypeScript will correct you if you change the form of an interface or type and eliminate a property that you thought wasn’t being utilised.

In essence, TypeScript is a JS linter. Alternatively, JS with compiler-friendly documentation.

As a result, unlike other languages like CoffeeScript (which adds syntactic sugar) or PureScript (which looks nothing like JavaScript), you don’t need to know much to get started creating TypeScript code.

Types are unnecessary in TypeScript, and any JS file is a valid TypeScript file. While the compiler will warn if your starting files contain type problems, it will return a JavaScript file that works as it did before. TypeScript will meet you wherever you are, and it’s simple to improve your skills over time.

Nevertheless, even if you don’t use TypeScript to its full potential, it’s a useful tool to have in your toolbox. It’s simple to start small and gradually expand your capabilities, learning and adding new features as you go. There’s no need to be terrified of TypeScript because it’s practical and accommodating to beginners.
