TypeScript is a superset of JavaScript with optional static typing.Static typing helps catch potential errors during development, before the code even runs.TypeScript provides better autocompletion, more accurate type-checking, and easier refactoring.As your JavaScript project grows, it becomes harder to manage large codebases with dynamic typing.TypeScript helps organise your code better, making it easier to maintain.TypeScript is designed to be easy to learn for JavaScript developers.Common types in TypeScript are string, number, boolean, object, and any (use with caution).Interfaces are useful when you want to ensure that objects follow a specific structure.Generics allow you to create functions, classes, and interfaces that work with any type, but still retain type safety.You can install TypeScript via npm, generate a TypeScript configuration file, write .ts files and compile it into JavaScript.
