TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It enhances JavaScript by adding static typing, which helps developers catch errors early and write more maintainable code. TypeScript offers features such as classes, modules, and interfaces for building robust components. Microsoft is the creator and primary maintainer of TypeScript.
Key features of TypeScript include static typing, support for the latest JavaScript features, and powerful tooling. Static typing allows developers to define the types of variables, function parameters, and return values, enabling compile-time checking and improved code quality. TypeScript also supports modern JavaScript features like async/await, decorators, and enhanced object literals, allowing developers to use the latest language features while maintaining compatibility with older browsers and environments. Furthermore, TypeScript provides excellent tooling, including code completion, refactoring, and debugging support, making it easier to develop and maintain large-scale JavaScript projects.
TypeScript is free and open-source. The TypeScript compiler, tsc, can be installed globally or locally within a project using npm (Node Package Manager). This flexibility allows developers to choose the installation method that best suits their needs and project requirements. TypeScript is readily available for use in various development environments and integrates well with popular editors and IDEs like Visual Studio Code.
