#JavaScript Or #TypeScript? Let’s decode it with Neeraj Walia the EZ way @ezsnippat #shorts

#JavaScript and #TypeScript are both programming languages primarily used for building web applications, but they have some key differences.

What is JavaScript ?
JavaScript is a high-level, interpreted programming language primarily used for web development.It was originally created to add interactivity and dynamic behavior to web pages. JavaScript is a multi-paradigm language, supporting imperative, functional, and object-oriented programming styles.

What is TypeScript ?
TypeScript is a superset of JavaScript developed by Microsoft. It adds optional static typing and other features to the language, making it more robust and maintainable, especially for large-scale applications. TypeScript code compiles down to plain JavaScript, so it can run on any JavaScript engine. It introduces features such as type annotations, interfaces, generics, and access modifiers, enhancing code quality and developer productivity. TypeScript provides better tooling support, including code editors with intelligent auto-completion, refactoring, and error checking.
It's particularly popular for building large-scale applications where code maintainability and scalability are important.

What are the major differences between the two?

1. Type System: One of the most significant differences is the presence of a static type system in TypeScript. JavaScript is dynamically typed, meaning types are resolved at runtime, while TypeScript introduces static typing, allowing developers to define types at compile time, catching errors early in the development process.

2. Tooling Support: TypeScript offers better tooling support compared to JavaScript, including features like intelligent code completion, refactoring tools, and static analysis, thanks to its statically typed nature.

3. Readability and Maintainability: TypeScript code tends to be more readable and maintainable, especially in larger codebases, due to features like type annotations, interfaces, and modules, which provide clearer contracts and structure to the code.

4. Learning Curve: JavaScript has a lower learning curve compared to TypeScript, as it doesn't require knowledge of static typing concepts. TypeScript requires developers to understand concepts such as types, interfaces, and generics.

5. Adoption: JavaScript has been around for much longer and is more widely adopted in the web development community. However, TypeScript's popularity has been growing rapidly, especially for large-scale projects and enterprise applications.
