Category: Typescript

TypeScript is a statically-typed superset of JavaScript that adds optional static typing and other features to the language. It was developed by Microsoft and released in 2012.

In TypeScript, developers can specify the data types of variables, function parameters, and function return values. The TypeScript compiler checks these types at compile-time to detect type errors before the code is executed, improving code reliability and reducing errors. TypeScript also includes features such as classes, interfaces, enums, and modules that are not available in traditional JavaScript.

The semantic definition of TypeScript can be described as a programming language that provides optional static typing, additional language features, and a type checking system to JavaScript. It is designed to make large-scale JavaScript applications more maintainable and reliable by detecting errors at compile-time and providing additional language features to facilitate code organization and reuse.
