Esprima: Syntax Validator


return 42; // should be inside a function

function f() {
  'use strict';

  var x = 042;

  with (z) {}
}

No result yet.

Unlike a typical code linter, this syntax validator does not care about coding styles and formatting.

If there is a syntax error, place the mouse cursor over the squiggly red line to reveal the detailed error description.
