Benchmark: Splice vs new Array Modulo

Script Preparation code:

var randomArray=Array.from({length: 1000}, () => Math.floor(Math.random() * 100));

Tests:

Splice
for (let i = randomArray.length - 1; i >= 0; --i) { if (randomArray[i] != 1) { continue; } randomArray.splice(i, 1); } return randomArray;
Copy to new
var newArray = []; for (let i = randomArray.length - 1; i >= 0; --i) { if (randomArray[i]%2 == 1) { continue; } newArray.push(randomArray[i]); } return newArray;
