Get first word of string

Okay, here is my code with details of what I have tried to do:

var str = "Hello m|sss sss|mmm ss";
//Now I separate them by "|"
var str1 = str.split("|");

//Now I want to get the first word of every split-ed sting parts:

for (var i = 0; i < codelines.length; i++) {
  //What to do here to get the first word of every spilt
}

So what should I do there? :\

What I want to get is :

• firstword[0] will give "Hello"

• firstword[1] will give "sss"

• firstword[2] will give "mmm"

Split again by a whitespace:

var firstWords = [];
for (var i=0;i<codelines.length;i++)
{
  var words = codelines[i].split(" ");
  firstWords.push(words[0]);
}

Or use String.prototype.substr() (probably faster):

var firstWords = [];
for (var i=0;i<codelines.length;i++)
{
  var codeLine = codelines[i];
  var firstWord = codeLine.substr(0, codeLine.indexOf(" "));
  firstWords.push(firstWord);
}
