Benchmark: Test samples - MeasureThat.net

Script Preparation code:

var domEl = document.createElement("span"), cls = " aaaaaaaaaaaaaaaaaaaaaa  bbbbbbbbbbbbbbbbb ", _hasCls = function(domEl, cls) {
			var found	= false,
				pos		= domEl.className.indexOf(cls);

			if (pos >= 0) {
				var endpos = pos + cls.length;
				found = endpos == domEl.className.length || domEl.className.charAt(endpos) == ' ';
			}

			return found;
		};

Tests:

Old method
if (!_hasCls(domEl, cls)) { if (domEl.className.length > 0) { cls = ' ' + cls; } domEl.className += cls; }
New check
cls.split(' ').forEach(function(onecls) { if (onecls) domEl.classList.add(onecls); });
New replace
cls.replace(/\s+/g, ' ').trim().split(' ').forEach(function(onecls) { domEl.classList.add(onecls); });
