TypeScript vs JavaScript

You've probably heard the TypeScript vs JavaScript which is better debate if you're into technology. Every web developer must have a good knowledge of these languages. Also, if you are someone looking for an in depth comparison between these languages then you are probably at the right place. Stay tuned with us, so that you can pick any one language by the end of this blog for your upcoming project.

In this blog, we'll talk about TypeScript vs JavaScript Know The Difference in detail. And after going through this blog you'll get to know typescript or javascript which is better. So, let's explore TypeScript and JavaScript which is better

What is Typescript?

The computer language TypeScript is highly typed, object-oriented, and compiled. It is based on JavaScript. TypeScript is an extension of JavaScript meant to give users better tools of any size.

The main person behind TypeScript is Anders Hejlsberg, who works at Microsoft as a designer for C#. It is a language and an open-source set of tools backed by Microsoft.

Typescript developers who use TypeScript say it is "JavaScript with syntax for types." In short, it's JavaScript with some extra features. 

TypeScript: Why Use It?

TypeScript adds to JavaScript to fill in the blanks and give typescript developers better tools at any size. Based on its competitors, TypeScript is easier to use and works better.

  • Simple to Use

One of the best things about TypeScript is its easy use. Getting started with TypeScript will be easy if you know some basic JavaScript. All TypeScript code is turned into a similar JavaScript code before it runs.

Any JavaScript (.js) file can be changed to a TypeScript (.ts) file to be compiled with other TypeScript files.

  • Being Portable

TypeScript is a lot like JavaScript. TypeScript code can be turned into JavaScript and run anywhere that JavaScript can run. Because of this, users can be sure that TypeScript will work on all computers, devices, and running systems that support JavaScript.

This differs from many TypeScript competitors, requiring a particular virtual machine (VM) or specific software settings.

  • Strong support for Developer Tools

Overall, TypeScript wants to make typescript developers more efficient and productive by reducing mistakes, making it easier to solve problems, and providing better tools.

TSC is also helpful for mobile developers because it can run in the background, helping build and integrate with IDEs. 

Features of TypeScript

  • Object-Oriented Language: TypeScript is an object-oriented programming language, so it has classes, interfaces, inheritance, modules, and more. You can write code for both client-side and server-side programming in TypeScript.
  • TypeScript supports JavaScript libraries: Typescript works with all JavaScript parts. It lets developers use TypeScript with JavaScript code that they already have. The JavaScript frameworks, tools, and other packages are easy to use here.
  • JavaScript is TypeScript: This means that code written in JavaScript and ending in.js can be turned into TypeScript by changing the ending to.ts and compiling with other TypeScript files.
  • TypeScript is Portable: It can be run on any browser, computer, or operating system, making it universal. TypeScript vs javaScript Know The Difference It can be used anywhere JavaScript can be used, and it doesn't depend on a unique virtual machine. 

What is JavaScript?

Scripting languages like JavaScript make web pages where people can interact. Because it follows the rules of client-side computing, it works perfectly in the user's computer browser. You can, however, use JavaScript with XML and REST APIs instead.

JS's main goal was to be a scripting language that works well with other scripting languages, like Visual Basic, which works well with C++. But JavaScript isn't suitable for making big, complicated apps. A few hundred lines of code for an app were supposed to be written.

Here are a few things that make JavaScript stand out:

  • Multi-platform, adaptable, and flexible
  • Client-side and server-side use are both possible.
  • Interpretation of light
  • Supports all browser
  • Not strongly typed JIT execution 

Differences Between Typescript and Javascript

Parameters TypeScript JavaScript
Creator In 2012, Microsoft introduced TypeScript. Netscape's Brendan Eich created JavaScript in 1995.
Definition TypeScript is a powerful object-oriented language that builds on top of JavaScript. It has both general and JS features that make it easier to use than JS. There are great programming languages like JavaScript that can be used to make dynamic web pages.
Typing You can use both static and dynamic typing in TypeScript. In JavaScript, you can only use dynamic typing. You can't use rigid typing.Typed very strongly.
Ecosystem TypeScript is a more robust and easy-to-use language that lets you type without moving your fingers. It is easy to read and write in JavaScript as it is a simple language that makes code compatible.
Compilation TypeScript needs to be put together. Putting together JavaScript doesn't need to be done.
Learning Curve TypeScript is a little hard to learn and needs specific programming knowledge. Plus, it's best if you already know how to use JavaScript. JavaScript can be used in many ways and is simple to learn.
Annotation With TypeScript, you need to use annotations to get the most out of its features. Annotations are not needed for JavaScript.
Prototyping The modeling tool can be used with the TypeScript language. JavaScript doesn't have a way to make prototypes.
Error Detection In TypeScript, errors are found or marked early on in the creation process. JavaScript is an interpreted language, which means that mistakes are only found when the code is being read.
Type There are more features in TypeScript than in other languages. It has interfaces, classes, static typing, and more. JavaScript is just a coding language that makes web pages work. It does not work with APIs.
Generics General features can be used with TypeScript. Using it, you can make parts that can be used repeatedly. There are no general features that JavaScript can use.
Community It takes a long time to learn TypeScript because it is a pretty new language. For some reason, not as many people use it as JavaScript. Although it is old, JavaScript is one of the most essential front-end languages. Because of this, it has a big group of creators.
Suitable TypeScript is an IDE-friendly language that focuses more on the front end. Any JS app will work well with it, but it works best for complicated apps. JavaScript works best for making web apps, apps for phones and computers, and games.
Execution TypeScript does not work in browsers by itself. JavaScript works on all platforms and computers because it runs straight in the browser.
Companies Using Asana, Clever, Screen Award, and other companies use TypeScript because it has more features. Because JavaScript is flexible and Node.js was released, many companies, including Netflix, Microsoft, PayPal, and more, started to use it.

Advantages of TypeScript 

Early Error Detection: Typescript has better tools for finding bugs early on. It ensures that developers save a lot of time and improves the quality of the code.

Static Typing: Declaring an object with a type ensures the code is well-organized. This also helps find bugs faster, makes people more productive, and speeds up fixing bugs and other problems.

Rich IDE support: TypeScript Development is better than JavaScript Development because it has better IDE support. TypeScript supports many Integrated Development Environments (IDEs), such as Visual Studio, WebStorm, Eclipse, and others. TypeScript or javaScript which is better this means that developers can use a single-user interface for various tasks. It has a text editor, a project editor, a debugger, and other tools.

Power of JavaScript: TypeScript is created to compensate for what JavaScript doesn't have. TypeScript has all the benefits of JavaScript because of its features. These are some of the pros:

  • TypeScript suits complicated projects because it uses object-oriented ideas like inheritance, classes, isolation, etc.
  • Cross-browser and cross-platform support

TypeScript Disadvantages

Compilation: When you use TypeScript, you have to compile.ts files before you can run them in a Node.js game. This adds one more step, making things more difficult for the creator. Because of this, many coders try to avoid TS.

Language is Hard to Learn: TypeScript is not as simple as JS. You need to know how to write scripts. Also, many coders think you should learn JavaScript before you try TypeScript. It changes developers' minds about whether to stick with JavaScript only.

Set Up Difficulties: TypeScript can be stressful for coders because it can be hard to set up processes. One of the biggest problems is that you have to write everything by hand. Also, Typescript feels stiff and rigid compared to JavaScript, which has less code and more freedom.

Advantages of JavaScript 

Interactive Languages: JavaScript's user interface (UI) helps you create significant interactive parts for a basic web page. It enables the coder and the user to learn, have fun, and talk to each other.

Supported Frameworks: JavaScript is the base language and is much older than TypeScript. Since many systems don't support TypeScript, this gives JavaScript an extra edge over TypeScript. TypeScript vs javaScript Know The Difference the tools and frameworks that come with JavaScript can speed up and simplify the coder's process.

Community: Developers still prefer JavaScript over TypeScript, regardless of its purposes and features. Because of this, many coders now support JavaScript. For newcomers or beginners, a group is a great place to find experienced people who share your interests and can help, guide, and push you.

Front-end and Back-end: JavaScript was first developed for the front end. However, since the most recent versions have been released, it also allows back-end work, which attracts more people who want to use JavaScript.

JavaScript Disadvantages

Browser Support: Code written in JavaScript can run on many computers. However, it often gives different computers different results, so there's a greater chance that many functions will only work in some systems.

Debugging: JavaScript's tools for finding errors and fixing bugs are better than those in other computer languages. They have to work more slowly and won't be able to use the early recognition feature in an emergency.

Front-end Security: Anyone who isn't supposed to be there can see the JavaScript code. TypeScript vs JavaScript Know The Difference which is better because the source code is so easy to access, it can make the data and web page less secure, leading to hacks.


So this was detailed blog post on "TypeScript vs JavaScript Know The Difference"

Now finally hope you have got your answer for typescript or javascript which is better

It depends upon your business needs which one to go for: TypeScript and JavaScript.

A classic coding language, JavaScript is still the first choice for many coders because it is flexible, has many extra features, and has a large community. It works well for small projects needing changeable web apps or mobile devices and computers.

TypeScript, on the other hand, is excellent for developers who work with big bases of code. It's a new language, but it works well for complicated projects because it has OOP ideas, general features, and a lot of help from IDEs.
