String Match. Match two strings with a tolerence

String Match.

function matchString(stringOne, stringTwo, tolerance){
	stringOne  = stringOne.toLowerCase().replace(/ /g,'');
	stringTwo = stringTwo.toLowerCase().replace(/ /g,'');
	var minLen = Math.max(stringOne.length, stringTwo.length);
	var bigLen = Math.min(stringOne.length, stringTwo.length);
	for(var i = 0, count = 0; i < minLen; i++){
		if(stringOne[i] === stringTwo[i]){
			count++;
		}
	}
	var ratio = count/bigLen;
	return ratio >= tolerance;
}
//Example
console.log(matchString("oscar", "Oskar", 0.8))
