TypeScript VS JavaScript
                     
TypeScript VS JavaScript
The two top technologies that are essential for developing web applications are 
TypeScript and JavaScript. As a result, among the wide community of developers, 
JavaScript has become the most well-liked programming language.
But since TypeScript was developed, the situation has drastically changed. Are 
you able to? Considered to be a more advanced version of JavaScript with some 
extra capabilities is TypeScript.
We must first comprehend the fundamental ideas behind TypeScript and 
JavaScript before we can understand how they differ from one another.
What is JavaScript?
JavaScript is a dynamic computer programming 
language. Its implementations enable the client-
side script to interact with users and create 
dynamic pages, and it is most frequently used as a 
component of web pages. It is an object-oriented 
programming language that may be interpreted.
LiveScript was the original name of JavaScript, but 
Netscape changed it to JavaScript, maybe in 
response to the buzz that Java was causing. 
LiveScript, the predecessor to JavaScript, had its 
debut in Netscape 2.0 in 1995. Netscape, Internet 
Explorer, and other web browsers all contain the 
general-purpose language's core.
What Is JavaScript Used For?
One of the best scripting languages for developing dynamic and interactive web-content-like 
apps in Javascript. The most widely used scripting language, JavaScript, is used on about 97% 
of all websites.
For creating various applications, such as software, hardware controls, and servers, JavaScript is 
a godsend. In addition, JavaScript is regarded as a well-known web-based language because of 
the way that it interacts naturally with web browsers.
● Easily adding impressive behaviour to create interactive web pages.
● Creating web and mobile apps.
● Building web servers and developing server applications.
● Speeding up the performance of the application.
● Developing front-end development as well as back-end development.
● Performing the data structure and validation on the web browser itself rather than on the 
server.
What is TypeScript?
TypeScript is an open-source language created by 
Microsoft that swiftly compiles JavaScript. 
TypeScript is a suite of technologies that makes 
web development simpler in addition to being a 
scripting language.
With additional capabilities specifically added to 
get around limitations in JavaScript libraries, 
TypeScript is JavaScript. It is advantageous for 
developers to have a foundational understanding of 
static type definitions and manage code complexity 
before using TypeScript. And it's crucial to 
comprehend the distinction between TypeScript 
and JavaScript.
What is TypeScript Used For?
Developers may create and supervise complex JavaScript applications using 
TypeScript, a superset of typed JavaScript. It is essentially JavaScript with the 
addition of strong static typing, code compilation, and object-oriented 
programming, to put it simply.
● Simplifying JavaScript code, making your application easier to read and debug.
● Quickly building web applications using highly productive web development 
tools for JavaScript IDEs and practices, like static checking.
● Quickly coding for all complex and large applications.
● Availing all the benefits of ES6 (ECMAScript 6), plus more productivity.
● You can develop mobile and web applications with a TypeScript web 
development company.
How Does TypeScript Differ from JavaScript?
● Typescript is a superset of JavaScript, while JavaScript is a scripting language 
that makes it possible to create dynamic web pages.
● JavaScript code does not require compilation, whereas Typescript code does.
● When TypeScript and JavaScript are compared, TypeScript supports 
prototyping, whereas JavaScript does not.
● In contrast to JavaScript, Typescript employs concepts like types and 
interfaces to describe the data being used.
● JavaScript is the best choice for small projects, while Typescript provides a 
robust type system with generics and JS capabilities for larger projects.

Difference Between Typescript and Javascript: 
The Comparison Table
JavaScript is a programming language that helps in the creation of interactive 
web pages, whereas TypeScript is a modern JavaScript development language. In 
contrast to JavaScript, which lacks such a concept, TypeScript employs ideas like 
types and interfaces to describe the data being used.
It's time to examine the idea of comparing TypeScript with JavaScript after 
looking at the fundamentals of both languages. So let's analyze how JavaScript 
and TypeScript vary by using a comparison table.

When to Choose JavaScript?
Small Projects: If you're working on a small web project or there aren't many 
available codes, JavaScript is a great alternative.
Active Framework Support: The developers might not be able to incorporate 
all the features into the same code if TypeScript does not support any commonly 
used frameworks like EmberJS.
Build Tools: TypeScript needs a build step when professionals need to create the 
JavaScript application's final run. However, developing JavaScript applications 
without any build tools is becoming increasingly unusual.
Testing Workflow: The advantages of switching to TypeScript could not exceed 
the costs if JavaScript experts are working on test-driven web development 
projects.
When to Choose TypeScript?
Compile Time Type Checking: Vanilla JavaScript is typically supported by 
TypeScript, and in such instances, type verification is carried out during runtime. 
It gradually increases the code's runtime overhead, which can be reduced by 
doing compile-time validation.
Large-Scale Projects: Programming languages like TypeScript are specifically 
made for creating complex systems that function well on a big scale or when 
numerous Typescript developers are working.
Easy to Use: You can make use of IntelliSense, which helps in identifying and 
navigating new interfaces if the professionals have engaged in React or Node JS 
development but are unfamiliar with its APIs. However, they both offer type 
definitions.
TypeScript VS JavaScript: Which is Better?
The developers can deal with removing some software irregularities during the 
web development project phase more easily by choosing TypeScript over 
JavaScript. Additionally, you can quickly safeguard the source code before 
releasing it for use.
We have seen the general idea of the main features that are available in both 
technologies in this essay comparing TypeScript vs JavaScript. In addition, we 
discovered the numerous optional options or terminology describing the 
differences between Javascript and Typescript.
