Ast-kit provides a suite of utilities to simplify working with Abstract Syntax Trees (ASTs) in JavaScript. It offers functions for traversing, manipulating, and querying ASTs generated by popular parsers like Esprima or Babel. With ast-kit, developers can streamline code analysis, transformation, and generation tasks by abstracting away the complexities of direct AST manipulation. It's useful for building linters, code formatters, and other tools that require deep code understanding.
