shift-interpreter/test/nostrict-eval.js

Shift-interpreter is an experimental JavaScript meta-interpreter useful for reverse engineering and analysis. One notable difference from other projects is that shift-interpreter retains state over an entire script but can be fed expressions and statement

exports.eval = function(src, context) {
  let result;
  if (context) {
    with (context) {
      result = eval(src);
    }
  } else result = eval(src);
  return result;
};
