Advanced JavaScript: A Deep Dive into the Core Concepts
Javascript vs Typescript: What is the Difference?
Introduction
What Is JavaScript
Nearly all online browsers now support Javascript, which was created by Netscape in 1995. However, Node.js may also be used with it for server-side programming. These scripts may be added to HTML documents, which the browser can then understand at runtime.
What Is TypeScript
It may be used to develop server-side and client-side web applications. Code written in TypeScript is converted into JavaScript code before being executed. For this, either Babel or the TypeScript compiler are employed. Typescript supports static typing. A feature called static typing checks the precision of a variable type during compilation. This makes it simpler to identify Type errors and address them quickly during compilation.

Code Comparison
The sample code below illustrates how Typescript and Javascript might be used to write the same piece of code. This snippet of code demonstrates how Typescript and Javascript can be used to add two integers.

Advantages
JavaScript over TypeScript
Although Typescript is superior to Javascript in most respects, Javascript still has several benefits over Typescript.
- As a scripting language, JavaScript may be run directly in a web browser. On the other hand, in order for the browser to execute TypeScript, it must first be built using the TypeScript compiler.
- Because Javascript allows static typing, which takes more time, it is advised for smaller applications rather than Typescript.
TypeScript over JavaScript
Because Typescript is a superset of Javascript, it has several more functionalities that Javascript does not have. As a result, the benefits that typescript has over Javascript are listed below:
- Javascript is preferred for smaller projects, but TypeScript is chosen for the creation of large or complicated applications.
- Javascript does not provide optional static typing for the language, whereas Typescript does.
- Compared to Javascript, Typescript makes code reorganization simpler.
- This speeds up the process of finding and repairing Typescript code issues.
- When compared to Javascript code, Typescript code is more condensed and well-organized.
- Because TypeScript is a type-checked language, developers can build programs with confidence and without worrying about unintentionally introducing data-related mistakes.
Websites Using TypeScript Vs JavaScript
Yahoo, Google, YouTube, Amazon, Facebook, Twitter, LinkedIn, Wikipedia, and other well-known websites have all been created using JavaScript.
Microsoft, Google, Alibaba Travels, Accenture, and other well-known companies are a few examples of those who use TypeScript.
