Just as an alternative approach:

'GEN000 AMA000 GaT000'.match(/\S/g).length;  // 18

However, the fastest solution should always be a single for loop:

var str = 'GEN000 AMA000 GaT000',
    count = 0;

for (var i = 0, len = str.length; i < len; i++) {
    if (str[i] !== ' ')
        count++;
}

var text = "GEN000 AMA000 GaT000";
var length = text.split(" ").join("").length;

console.log(length);

@katspaugh This answer is not exactly the same as yours.

@katspaugh My answer is in different place :)

Try this simple solution,

alert(str.replace(/\s/g, "").length);
