# TypeScript

> Source: https://docs.strapi.io/cms/typescript

TypeScript adds a type system layer to Strapi applications, enabling type-safe code and automatic type generation. Create a new TypeScript project with the `--typescript` flag or add TypeScript support to an existing project.

[TypeScript](https://www.typescriptlang.org/) adds an additional type system layer above JavaScript, which means that any valid JavaScript code is also valid TypeScript code. In the context of Strapi development, TypeScript allows for a more type-safe codebase for your application, and provides you with a set of tools for automatic type generation and autocompletion.
