  TypeScript is a strongly typed programming language that builds on JavaScript,
  adding optional static type checking and other features. Developed and maintained
  by Microsoft, TypeScript compiles to plain JavaScript and is widely used for
  large-scale web applications, Node.js services, and developer tooling. The
  TypeScript Compiler API and Language Service API enable programmatic compilation,
  type checking, code transformation, and IDE integrations.

    name: TypeScript Compiler API
    description: >-
      Programmatic access to the TypeScript compiler. The Compiler API allows
      developers to parse TypeScript files into ASTs, perform type checking,
      emit JavaScript, and transform code programmatically.

      The TypeScript Transform API enables custom AST transformations during
      compilation. Transformers can modify, add, or remove nodes in the
      TypeScript AST before code emission.
