Benchmark: reduce or forEach

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

var a = Array.from({length:100},()=>Math.random()< 0.5 ? { igvTax: 0, subtotal: 100*Math.random()}: { igvTax: 1, subtotal: 100*Math.random()});
var b = 0;

Tests:

Reduce
b = a.reduce((acc, { subtotal, igvTax })=>{ if(!igvTax) return acc return acc += subtotal },0)
For Each
a.forEach(({ subtotal, igvTax }) => { if(!igvTax) return b += subtotal })
