What is TypeScript?
TypeScript is strongly typed. This makes it better to debug (during compile time) which is a more efficient way to code for large projects. TypeScript programs typically consist of modules, functions, variables, comments, expressions, and statements – just like any other full-fledged programming language.
When the code becomes huge, complex to handle, and prone to errors, it is better if the errors are caught during compile time itself. That is where TypeScript helps.
Companies that use TypeScript include Microsoft, Slack, Medium, and Accenture.
Some of TypeScript’s most prominent features are:
- Easy to maintain and enhances project productivity.
- Static typing and annotations are possible.
- Supports object-oriented features like interface, inheritance, and classes.
- Easy to debug and early detection of errors.
- Supports ES6 (ECMAScript) that offers easier syntax to handle objects and inheritance features.
- Good full-fledged IDE support.
