It's better to use regex here, if there are chances of multiple spaces in the array elements.

  1. Join the array elements by space
  2. Extract non-space characters from string using regular expression

var array = ["       no yes     ", "     maybe     certainly  "];

var array2 = array.join('').match(/\S+/g);

document.write(array2);
console.log(array2);

Very simple, seems efficient.
@rrowland not so efficient jsperf.com/match-vs-split-22, as you can see split more faster than match
@Alexander You might want to recheck that again with updated answer. jsperf.com/match-vs-split-22/2
@Tushar as I see split faster than match jsperf.com/match-vs-split-22, and I can say much faster
@Alexander That is with the old code. I've updated code. Kindly check again on jsperf.com/match-vs-split-22/2

You can join all elements in array, and after split it to array, like so

// var array = ["no yes", "maybe certainly"];
var array = ["no yes     ", "    maybe    certainly"];
var array2 = array.join('').trim().split(/\s+/g);

console.log(array2);

var array = ["no yes", "maybe certainly"]

answer = converfunction(array);

function converfunction(array){
return array.toString().replace(',',' ' ).split(' ')
}

Check with var array = [" no yes ", " maybe certainly "];
