# Easy Debugging

Chevrotain is an internal JavaScript DSL. This means that Chevrotain grammars are just plain JavaScript source code without any additional levels of abstraction as in parser generators (EBNF vs generated code).

In practical terms this means that debugging a Chevrotain parser is the same as debugging any other JavaScript code, just setup breakpoints or debugger statements using your favorite IDE.

For example:

$.RULE("statement", () => {
  debugger;
  $.RULE("objectItem", () => {
    $.CONSUME(StringLiteral)
    debugger;
    $.CONSUME(Colon);
    $.SUBRULE($.value);
  });
