Benchmark: Convert Date object to number(+ vs getTime vs Number), and for i vs foreach

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

let e = [];
let d = new Date();
for(let i=0; i<100; i++){
  e.push(new Date(d));
  d.setDate(d.getDate()+1);
}

Tests:

Plus for i
for(let i=0; i<100; i++){ +e[i]; }
getTime() for i
for(let i=0; i<100; i++){ e[i].getTime(); }
Number() for i
for(let i=0; i<100; i++){ Number(e[i].getTime()); }
Plus foreach
for(let i of e){ +i; }
getTime foreach
for(let i of e){ i.getTime(); }
Number foreach
for(let i of e){ Number(i); }
