Test name	Executions per second
With cache	16079.3 Ops/sec
Without cache	8060.0 Ops/sec
While loop (as performance reference)	16006.4 Ops/sec

Script Preparation code:

var arr = [...Array(1000).keys()];

Tests:

With cache
let sum = 0; for (let i = 0, arrLen=arr.length; i < arrLen; i++){ sum += arr[i]; }
Without cache
let sum = 0; for (let i = 0; i < arr.length; i++){ sum += arr[i]; }
While loop (as performance reference)
let sum = 0; let i = arr.length; while(i--){ sum += arr[i] }
