Traduzione codice JS

[nyles82]

Ciao a tutti....^^

scusate sto facendo un progetto e purtroppo mi hanno passato delle funzioni in un linguaggio che non è il mio... sto parlando di javascript

qualcuno mi potrebbe dire in soldoni cosa fanno le singole funzioni?

grazie anticipatamente

buttons.Button = Class.create({

  /**
   * params:
   *   
   * handler (optional) - the function to be invoked as handler of the click event on the button
   * domElement (optional) - the element of the button
   * enabled (optional) - If unset defaults to false
   * domElementName (optional) - If the dom creation is deferred
due to different windows button usage, this is used to create the dom
   * domId (optional) - when created, the dom element id will be set to domId
