Benchmark: Uint8array equality benchmark

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

window.data1 = new Uint8Array([...Array(1000).keys()].map(k=>k%8))
window.data2 = new Uint8Array([...Array(1000).keys()].map(k=>k%8))


window.arrayEquals = function(a, b) {
    return Array.isArray(a) &&
        Array.isArray(b) &&
        a.length === b.length &&
        a.every((val, index) => val === b[index]);
}

Tests:

_.isEqual Level 1
_.isEqual(window.data1, window.data2)
JSON.stringify Level 1
JSON.stringify(window.data1) === JSON.stringify(window.data2);
Naive array equals
window.arrayEquals(window.data1, window.data2)
