Two Filter vs Reduce

Benchmark created on

Setup

var addons = [];

for (let index = 0; index < 1000; index++) {
  var innerPrice = {
    amount: Math.round(Math.random() * 10),
    test: 'x',
    more: 'data',
    just: 'included',
    for: 'fun',
  };
  var price = (index % 2) ? {
    recurring: { ...innerPrice }
  } : {
    upfront: { ...innerPrice }
  };

  addons.push({
    name: index.toString(),
    price: { ...price },
    id: index,
    data: {
      just: 'some',
      random: 'data',
    }
  })
}
