Benchmark: Array filtering performance

Script Preparation code:

var arr = []
for (var i = 0; i < 1_000_000; i++) {
  arr.push({id: i})
}

Tests:

Array.filter
var result = arr.filter(x => x.id % 2 === 0)
For loop
var result = [] var l = arr.length for (var i = 0; i < l; i++) { var value = arr[i] if (value.id % 2 === 0) { result.push(value) } }
