javascript - Converting ArrayLike Object -

Is there no way to change an object in an array like an array so that all array methods can be used with it ? Also, for each array-like object,

  [] Prototype I want to use this "corn" string directly for each loop on the air cal ("mieger", FN)   
  
 what I want to do. But before that I need to convert it to an array. There is any possibility or any move that works for all array-like objects. Thank you.   
 
 
 instead of  slices  instead of  forEach  (< Code> piece  will simply make an array out of it):  
  Array.prototype.slice.call ("maizere"). Map (function (l) {return l + 'foo';}) pre (function (l) {console.log (l);});   
 This will work for array-like objects such as  nodelists  s,  logic  and strings.
