Javascript Vs typescript

1. Type System:JavaScript: JavaScript is a dynamically typed language. This means that variable types are determined at runtime, and you don't have to explicitly specify the data type of a variable.TypeScript: TypeScript is a statically typed superset of JavaScript. It adds a strong static type system, allowing you to declare variable types and catch type-related errors during development. This can lead to more robust and maintainable code.
2. Development Experience:JavaScript: JavaScript offers flexibility and quick development but can be error-prone, especially in larger projects, due to its dynamic typing. TypeScript: TypeScript provides better tooling and code quality through static type checking, making it easier to catch and prevent common programming mistakes. This is especially helpful for larger projects and teams.
3. Compatibility:JavaScript: JavaScript code can run in any browser or runtime environment that supports it. It has a broad ecosystem and a massive community. TypeScript: TypeScript code needs to be transpiled into JavaScript before it can run in a browser or other JavaScript environments. However, this transpilation process helps catch errors and enforces type safety.
4. Codebase Scalability:JavaScript: While JavaScript can be used for both small and large projects, it can become challenging to manage as a codebase grows, as it lacks strict type checkingTypeScript: TypeScript is designed with large codebases in mind. Its type system and tooling make it easier to maintain and refactor code as the project size increases.
5. Adoption and Community:JavaScript: JavaScript has been around for a long time and has a massive, established community and ecosystem of libraries and frameworks. TypeScript: TypeScript's popularity has been growing steadily, and it's often used in conjunction with popular JavaScript libraries and frameworks. It has a strong developer community and support from major tech companies.

Examples :

1. JavaScriptlet var1 = "Hello";var1 = 10;console.log(var1);
2. TypeScript

let var1: string = "Hello";

var1 = 10;

console.log(var1);
