Benchmark: Search - forEach vs reduce vs map vs filter vs for

Script Preparation code:

var arr = [];
for (var i = 0; i < 12345; i++) {
  arr[i] = i;
}
var result = [
[],[],[],[],[]
]

Tests:

forEach
arr.forEach(item => item == 12344 && result[0].push(item));
reduce
result[1] = arr.reduce((lastValue, item) => { if (item == 12344) return item; });
map
arr.map(item => (item == 12344 && result[2].push(item)));
filter
result[3] = arr.filter(item => (item == 12344));
for
for (var j = 0; j < arr.length; j++) { if(arr[i]==12344) result[4].push(arr[i]) }
