Benchmark: for loop filter vs native array.filter

Script Preparation code:

var array = [...Array(100000).keys()];

function fastFilter(arrayToFilter, cb) {
    const stack = []

    for (let i = 0; i < arrayToFilter.length; i += 1) {
        const item = arrayToFilter[i]

        if (cb(item, i)) {
            stack.push(item)
        }

    }

    return stack
}

Tests:

Array.prototype.filter
array.filter(n => n === 99999)
for loop filter
fastFilter(array, n => n === 99999)
