Benchmark: Array.from() vs new Array() without callback

Tests:

new Array()
const renderEmptyPricingTableColumns = ({ length }) => { const emptyPeriodArray = new Array(length).fill(null); return emptyPeriodArray.map((_, idx) => ( "empty-period-"+idx ?? 0 )); }; renderEmptyPricingTableColumns({length : 500})
Array.from()
const renderEmptyPricingTableColumns = ({ length }) => { const emptyPeriodArray = Array.from({length}); return emptyPeriodArray.map((_, idx) => ( "empty-period-"+idx ?? 0 )); } renderEmptyPricingTableColumns({length : 500})
