Benchmark: Filter + join vs while + str

Script Preparation code:

var arr = ['text', 'text', false && 'text', true && 'text', 'text', undefined, null, 'last str'];
var repeats = 10000;

var cnF = (...args) => {
    return args.filter(cls => (
        cls !== undefined && cls !== null && cls !== false
    )).join(' ')
};

var cnW = (...args) => {
    var i = 0
    var str = ''
    while (i < args.length) {
        var cls = args[i]
        if (cls !== undefined && cls !== null && cls !== false) {
            if (str.length > 0) str += ' '
            str += cls
        }
        i++
    }
    return str
};
