for..of
let r=0; for (v of arr) { r+=v; }
for
let r = 0; const l = arr.length; for (var i=0; i < l; i++ ) { r += arr[i]; }
foreach
let r = 0; arr.forEach( (v) => r += v );
for..of with const
let r=0; for (const v of arr) { r+=v; }
for again
let r = 0, i=0; const l = arr.length; for (;i < l;) { r += arr[i++]; }
