Split split is the opposite of join, which is used to divide a string into an array of strings.   Stringobject.split (A,B) This is its syntax. A is the necessary decision from a this division. B is not a must, optional. This parameter specifies the maximum length of the array to return. If this argument is set, the returned substring will not be more than the array specified by this parameter.   If this argument is not set, the entire string is split, regardless of its length. Note that the returned array does not include a itself; hint and comment note: If an empty string ("") is used as a, then each character in the Stringobject is split.   Note: The actions performed by String.Split () are the opposite of those performed by Array.join. Example var str= "Hello world!"; document.write (Str.split ("") + "<br/>"); document.write (Str.split ("") + "<br/>");   document.write (Str.split ("", 3) + "<br/>"); Return to H,e,l,l,o, w,o,r,l,d,! hello,world! H,e,l
