Benchmark: cached Intl.NumberFormat vs new Intl.NumberFormat vs toLocaleString currency loop

Tests:

cached Intl.NumberFormat
window.a = window.a || new Intl.NumberFormat('en-US', { style: 'decimal', maximumFractionDigits: 2, minimumFractionDigits: 2 }); for (let i = 10000; i< 10100; i++) { window.a.format(i) }
new Intl.NumberFormat
for (let i = 10000; i< 10100; i++) { new Intl.NumberFormat('en-US', { style: 'decimal', maximumFractionDigits: 2, minimumFractionDigits: 2 }).format(i); }
toLocaleString
for (let i = 10000; i< 10100; i++) { i.toLocaleString('en-US', { style: 'decimal', maximumFractionDigits: 2, minimumFractionDigits: 2 }) }
