Benchmark: map vs for loop cloneNode

Script Preparation code:

let V=[document.createElement('div'),document.createElement('p'),document.createElement('span'),document.createElement('a')]
let x=[0,0,0,0,1,2,3,3,2,1,0,0,1,2,  0,0,0,0,1,2,3,3,2,1,0,0,1,2, 0,0,0,0,1,2,3,3,2,1,0,0,1,2, 0,0,0,0,1,2,3,3,2,1,0,0,1,2, 0,0,0,0,1,2,3,3,2,1,0,0,1,2, 0,0,0,0,1,2,3,3,2,1,0,0,1,2]
let cn=['a','b','c','a','b','c','a','b','c','a','b','c','a','b']
let y=[[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a'],[0,'a']]
let z=[0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a',0,'a']
let w=[0,0,0,0,1,2,3,3,2,1,0,0,1,2,'a','b','c','a','b','c','a','b','c','a','b','c','a','b']
let B=(a,b)=>{
  let d=V[a].cloneNode();
  d.className=b;
  return d;
}

Tests:

for loop
let z = x.map(i => V[i].cloneNode());
combined map
let z = y.map(i => B(i[0],i[1]));
looped together
let z=Array(14);for(let i=0;i<14;++i){z[i]=V[x[i]].cloneNode();z[i].className=cn[i];}
looped together double list
let z=Array(14);for(let i=0;i<14;++i){z[i]=V[w[i]].cloneNode();z[i].className=w[i+14];}
