Benchmark: Reduce(spread) vs Map

Script Preparation code:

var a = [];
for (let i = 0; i < 50; i++) {
    a.push(Number(i) / 10)
}
var mapping = x => ({
    id: x
})
var reducing = (acc, x) => {
    return [...acc, {
        id: x
    }]
}

Tests:

Reduce
a.reduce(reducing, [])
Map
a.map(mapping)
