title: ES6 how to get source code for filter( ) method
body: <p>I've tried to reproduce the method <code>filter</code> so far I have got:</p>
  
  <pre><code>function filtre(...[T,x,y]){
  let tabPersF = [];
  for (let pers of T) {
      if (x(...[pers,y])) {
        tabPersF.push( pers ); 
       }
  
  }
    return tabPersF;
  }
  </code></pre>
  
  <p>How about it?.</p>
