Benchmark: Passing existing array vs spreading twice

Script Preparation code:

data = [...Array(1000).keys()]

Tests:

Passing array directly to second function
function first(...data){ const res = data.map((n)=> parseInt(n)) return second(res) } function second(data){ const reducer = (acc, n)=> acc + n return data.reduce(reducer, 0) } first(...data)
Spreading array an extra time
function first(...data){ const res = data.map((n)=> parseInt(n)) return second(...res) } function second(...data){ const reducer = (acc, n)=> acc + n return data.reduce(reducer, 0) } first(...data)
