Benchmark: classcat, clsx, obj-str, vanilla

HTML Preparation code:

<script type="module">
    import classcat from "https://unpkg.com/classcat?module"
    window.classcat = classcat
</script>
<script type="module">
    import objstr from "https://unpkg.com/obj-str?module"
    window.objstr = objstr
</script>
<script src='https://unpkg.com/clsx@latest/dist/clsx.min.js'></script>

Script Preparation code:

var obj = {
    one: true,
    abcd: Math.random() <= 0.5,
    efghijkl: Math.random() <= 0.5,
    mnopqrstuvwxyz: Math.random() <= 0.5,
    efghijklmnopqrstuvwxyz: Math.random() <= 0.5,
    abcdefghijklmnopqrstuvwxyz: Math.random() <= 0.5,
    abcd: Math.random() <= 0.5,
    efghijkl: Math.random() <= 0.5,
    mnopqrstuvwxyz: Math.random() <= 0.5,
    efghijklmnopqrstuvwxyz: Math.random() <= 0.5,
    abcdefghijklmnopqrstuvwxyz: Math.random() <= 0.5,
    two: false,
    three: true
}

var arr = [
    true && "one",
    Math.random() <= 0.5 && "abcd",
    Math.random() <= 0.5 && "efghijkl",
    Math.random() <= 0.5 && "mnopqrstuvwxyz",
    Math.random() <= 0.5 && "efghijklmnopqrstuvwxyz",
    Math.random() <= 0.5 && "abcdefghijklmnopqrstuvwxyz",
    Math.random() <= 0.5 && "abcd",
    Math.random() <= 0.5 && "efghijkl",
    Math.random() <= 0.5 && "mnopqrstuvwxyz",
    Math.random() <= 0.5 && "efghijklmnopqrstuvwxyz",
    Math.random() <= 0.5 && "abcdefghijklmnopqrstuvwxyz",
    false && "two",
    true && "three",
]
