TypeScript vs JavaScript — What are the Differences and Which One Should You Choose?

For many years, JavaScript has been the preferred language for creating web apps. However, with the introduction of TypeScript, developers now have another choice. We'll examine the fundamental distinctions between TypeScript and JavaScript in this blog post to assist you in selecting the language that will best meet your web development requirements.

What is TypeScript?

The addition of features like type annotations, interfaces, and classes makes TypeScript a statically typed superset of JavaScript. Microsoft created it, and because of its capacity to identify mistakes at the compile stage and offer better code organisation, it has grown in favour among developers.

What is JavaScript?

The dynamically typed scripting language known as JavaScript was initially developed for the internet. It is used for front-end, back-end, and even mobile app development and is supported by all popular browsers.

Differences between TypeScript and JavaScript

  • Type annotations: Unlike JavaScript, TypeScript enables programmers to add type annotations to variables, functions, and parameters.
  • Classes and Interfaces: compared to JavaScript, TypeScript offers classes and interfaces.

  • Compilation: Unlike JavaScript, which a browser or server may execute directly, TypeScript must first be built before it can be used.
  • Compatibility: Code written in TypeScript cannot be used in JavaScript, but TypeScript code written in JavaScript can.

Benefits of using TypeScript

  • Better code quality: TypeScript's ability to detect problems during compilation results in fewer runtime errors and higher-quality code overall.
  • Better tooling: When it comes to code completion, refactoring, and debugging, TypeScript outperforms JavaScript in terms of tool support.
  • Greater scalability: As the codebase expands, TypeScript's improved organisation and structure make the code more scalable.

Benefits of using JavaScript

  • Simplicity: Compared to TypeScript, JavaScript is a simpler language, making it simpler to learn and use.
  • Flexibility: In addition to web development, JavaScript can also be used to create desktop and mobile applications.
  • Compatibility: All of the main browsers support JavaScript, which doesn't require compilation to be used.

Which one should you choose?

The decision between TypeScript and JavaScript depends on the requirements and needs you have. TypeScript is a fantastic choice if you require improved code organisation, quality, and scalability. JavaScript can be a better option if you prefer a more convenient, straightforward language.


Conclusion:

Overall, TypeScript and JavaScript are two powerful web development languages ​​with unique features and benefits. While TypeScript is a newer language that offers better code quality and organization, JavaScript remains a popular choice due to its simplicity, flexibility, and broad compatibility. Ultimately, deciding on one of these will depend on your specific needs and requirements.
