Make the JS console "clear" function act the terminal "clear" command

console-clear.js

(function(){
  if (typeof clear !== 'undefined') {
    var oldClear = clear;
    Object.defineProperty(window, 'clear', {
      get: function() {
        oldClear();
        return oldClear;
      }
    });
  }
})();
// Now we can type "clear" instead of "clear()" in developer consoles.

Now you can use either "clear()" or "clear" in the console to clear the console.
