Difference Between Type Script vs Java Script
Introduction
We'll look at the characteristics of both languages and see what we can accomplish with them. The distinctions between Javascript and Typescript would also be covered in the session. We'll look at a little code sample created in each of these languages as well.
The goal of this lesson is to thoroughly teach TypeScript and JavaScript. Despite the fact that both languages are used to construct web applications, we will learn the distinctions and applications of each.
What Does JavaScript Mean?
Netscape created Javascript in 1995 as a client-side scripting language. With the help of Node.js, it may also be used for server-side scripting. Because it is not compiled before execution, it is considered a scripting language.
Instead, at runtime, each line or instruction is parsed individually. Scripts are the applications written in Javascript. The browser interprets and executes these scripts immediately. Almost every web browser supports it.
We can use Javascript to make dynamic web sites. Displaying the most recent news updates, animated visuals, verifying user inputs, altering information without refreshing the website, and so on.
Javascript may be used to implement all of these capabilities. These scripts may be inserted in HTML pages, which the browser can parse at runtime.
What Exactly Is TypeScript?
Typescript is an object-oriented programming language managed by Microsoft. It was first made public in October of 2012. It is, in reality, a Javascript superset. TypeScript was created to address the shortcomings of JavaScript.
It comes very handy while creating huge apps. It may also be used to create JavaScript apps that run on both the client and the server. Before being executed, TypeScript code is translated to JavaScript code. The TypeScript compiler or Babel are used for this.
Static typing is supported by Typescript. Static typing is a compiler feature that verifies the accuracy of a variable type. This feature aids in the detection of Type problems and their correction at build time.
Comparison Table Between JavaScript and TypeScript
| JavaScript |
TypeScript |
- It's a scripting language that makes interactive web pages possible.
|
- It's a Javascript superset. It provides all of the functionality of Javascript as well as a few more.
|
- Brendan Eich of Netscape designed it, and ECMA maintains it.
|
- Anders Hejlsberg invented it at Microsoft, and Microsoft currently maintains it.
|
- When Javascript code is executed, it is interpreted.
|
- Before being executed, Typescript code is compiled.
|
- Type Static typing is not supported by Javascript.
|
- Both static and dynamic typing are supported by Typescript.
|
- It is best used for modest jobs.
|
- It comes in handy while working on huge or complicated tasks.
|
- The browser executes Javascript code directly.
|
- Before being executed by the browser, Typescript code is first compiled by the Typescript compiler.
|
- Prototyping is not possible with Javascript.
|
- In TypeScript, prototyping is feasible
