why I got error when "push" the element to array list in javascript?

Question

I wrote the code, but I don't know where the mistake is?

I want to fill out the numberList array from 1 to 6 by for/loop and push.

let numberList = [];


for (let i = 0; i <= 6; i++) {
  numberList[i].push();
}
console.log(numberList);

Your current syntax is wrong . The actual Array.prototyp.push() syntax is like below,

push(element0)
push(element0, element1)
push(element0, element1, ... , elementN)

Code: : If want to fill out the numberList array from 1 to 6 by for/loop and push, then start i from 1 not 0

 let numberList = []; for (let i = 1; i <= 6; i++) { numberList.push(i); } console.log(numberList);
