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

Script Preparation code:

const num2code = (n)=> n < 10 ? 0x30 + n : n < 36 ? 0x61 + (n - 10) : 0x41 + (n - 36);
const getInt = (()=>{r=Math.random;f=Math.floor;return (a=0,b=0x100000000)=>f(r()*(b-a))+a})();
const getStr = (n)=>String.fromCharCode(...(new Int32Array(n)).map(()=>num2code(getInt(0,62))));

const N = 0x10000;

Tests:

push
const arr = []; for(i=0; i<N; i++) arr.push(getInt());
arr.length++;
const arr = []; for(i=0; i<N; i++) arr[arr.length] = getInt();
arr[j++]
const arr = []; let j = 0; for(i=0; i<N; i++) arr[j++] = getInt();
