Detect if string contains any spaces

Question

How do I detect if a string has any whitespace characters?

The below only detects actual space characters. I need to check for any kind of whitespace.

Answer 1

var string  = 'hello world';
var arr = string.split(''); // converted the string to an array and then checked: 
if(arr[i] === ' '){
   console.log(i);
}

I know regex can do the trick too!
