Script Preparation code:

const arr = new Array(1000);
window.arr = arr;
for (let i = 0; i < arr.length; i++) {
    arr[i] = (Math.random() * 1000 >> 0) + 50
}

Tests:

const indexArr = new Array(1000)
for(let i = 0;i < arr.length;i++){
	indexArr[i]=arr[i]
}

 
const indexArr = new Array(1000)for(let i = 0;i < arr.length;i++){    indexArr[i]=arr[i]}

const pushArr = new Array(1000)
for(let i = 0;i < arr.length;i++){
	pushArr.push(arr[i])
}

 
const pushArr = new Array(1000)for(let i = 0;i < arr.length;i++){    pushArr.push(arr[i])}
