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

Script Preparation code:

let objListA = [];
let objListB = [];
for(i=0;i<0x10;i++)
{
  objListA[i] = Object.create(objListA[-1] ?? null);
  objListB[i] = Object.create(null);
  objListA[i]['prop'+i] = i * i;
  objListB[i]['prop'+i] = i * i;
  Object.setPrototypeOf(objListB[i],objListB[i-1]??null);
}

Tests:

Object.create
let objListA = []; for(i=0;i<0x10;i++) { objListA[i] = Object.create(objListA[-1] ?? null); objListA[i]['prop'+i] = i * i; }
Object.setPrototypeOf
let objListB = []; for(i=0;i<0x10;i++) { objListB[i] = Object.create(null); objListB[i]['prop'+i] = i * i; Object.setPrototypeOf(objListB[i],objListB[i-1]??null); }
