**
JavaScript
**
Dynamic Typing: JavaScript is a dynamically typed language, meaning that variables can hold any value, and types are checked at runtime.
Flexibility: The flexibility of JavaScript allows for rapid development and prototyping.
Compatibility: JavaScript is natively supported by all web browsers and is the standard language for web development.
Ecosystem: JavaScript has a vast ecosystem with numerous libraries and frameworks like React, Angular, and Vue.js.
Popularity: JavaScript is one of the most widely used programming languages in the world.
**
TypeScript
**
Static Typing: TypeScript is a statically typed superset of JavaScript, meaning that it introduces type checking at compile time. This can help catch errors early in the development process.
Type Annotations: Developers can explicitly define types for variables, function parameters, and return values, making the code more readable and maintainable.
Tooling: TypeScript’s type system enables better tooling support, such as autocompletion, navigation, and refactoring in IDEs.
Compile Step: TypeScript code must be transpiled to JavaScript before running in a browser or Node.js environment.
Adoption: TypeScript is increasingly adopted in larger projects and by companies that value maintainable and scalable codebases.
**
Summary
**
JavaScript is more flexible and doesn’t require type annotations, making it suitable for quick prototyping and smaller projects.
TypeScript adds a layer of static typing and type safety, which can improve code quality and maintainability, especially in larger projects.
In essence, TypeScript offers all the features of JavaScript but with additional capabilities that help write safer and more predictable code.
