I have a string:

hello

and I want to add a space between each character to give:

h e l l o

What is the best way to do this?

---

"hello".split('').join(' '); // "h e l l o"

---

var text = "hello";
var betweenChars = ' '; // a space

alert(text.split('').join(betweenChars));

---

try:

var hello = 'hello';
var test = '';

for(var i=0; i<hello.length; i++){
   test += hello.charAt(i) + ' ';     
}

alert(test);
