Test name
Executions per second
div by 2
87.8 Ops/sec
div by 2.0
89.1 Ops/sec
multiply by 0.5
86.6 Ops/sec
Script Preparation code:
const length = 100000; const tmp_nums=[]; for (let i = 0; i < length; i++) { tmp_nums.push(Date.now() + Math.random()); } nums = [...tmp_nums]; nums_len = length;
Tests:
div by 2
const length = nums_len; for (let i = 0; i < length; i++) { nums[i] /= 2; }
div by 2.0
const length = nums_len; for (let i = 0; i < length; i++) { nums[i] /= 2.0; }
multiply by 0.5
const length = nums_len; for (let i = 0; i < length; i++) { nums[i] *= 0.5; }
