Benchmark: Classnames vs CLSX vs custom using reduce

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/classnames/2.2.6/index.min.js'></script>
<script src='https://unpkg.com/clsx@1.1.0/dist/clsx.min.js'></script>

Script Preparation code:

var str = 'style';
var obj = {
 	 'style-2': true,
  	 'style-3': false,
 	 'style-4': true,
}
var arr = ['style-5', 'style-6']

Tests:

classnames
let result = window.classNames(str, obj, arr, 'test classname')
clsx
let result = window.clsx(str, obj, arr, 'test classname')
Custom implementation using reduce
function maybeJoin(a,b) { return b ? a + " " + b : a; } function customCn(...args) { return args.reduce((acc, curr) => { if (!curr) return acc; if (typeof curr === "string") { return maybeJoin(acc,curr); } if (Array.isArray(curr)) { return maybeJoin(acc, curr.filter(Boolean).join(" ")); } if (typeof curr === "object") { return maybeJoin(acc, Object.keys(curr).filter((key) => key && curr[key]).join(" ")); } return acc; }, ''); } let result = customCn(str, obj, arr, 'test classname');
