JavaScript console helpers: a few functions I use here or there in the console

console-helpers.js

// simplify testing things like regexes
function eqs() {
  var a = [].slice.call(arguments);
  var fn = a.pop();
  var i, actual;
  for (i = 0; i < a.length; i += 2) {
    actual = fn(a[i]);
    if (actual !== a[i+1]) {
      console.error('"%s" !== "%s" (%s)', actual, a[i+1], a[i]);
    }
  }
}

console.log('console helpers loaded | https://gist.github.com/cowboy/9973862');
