Benchmark: Array initialization: preallocate a typed array vs vanilla and push

Tests:

Preallocate

var N = 10000;
var result = new Uint8Array(N);
for (var i = 0; i < N; i++) {
  result[i] = i;
}

var N = 10000;var result = new Uint8Array(N);for (var i = 0; i < N; i++) {  result[i] = i;}

Push

var N = 10000;
var result = [];
for (var i = 0; i < N; i++) {
  result.push(i);
}

 
var N = 10000;var result = [];for (var i = 0; i < N; i++) {  result.push(i);}
