Two dimensional array

The push method only adds to the end.

When you use push, you don't specify the place, the new items always go on the end of the array.

Push method, no. As Steven indicated, push only adds items to the end of an array, but you can add content using the splice method (with a for loop if you feel like it...)

let fruit = ["banana", "orange", "apple"];
const animal = "cat";
let num = 0;

for(item in fruit){
    fruit.splice(num, 0, animal);
    num = num + 2;
};
console.log(fruit);

Output:

[ 'cat', 'banana', 'cat', 'orange', 'cat', 'apple' ]

The first parameter in the splice method specifies where in the array (fruit) you would like to add your content. I indicated here I would like to use my variable num, but this can be a static number. The second parameter specifies how many items to remove from the array, which I indicated here as 0. If there is an item already in the fruit[num] position, it will be pushed to the next position within the array. The third parameter is what content would you like to place inside the array (fruit) at our fruit[num] position.

I chose a dynamic variable to demonstrate when you might want to use a for loop, but if you are looking to place something at a specific location within an array, it would be best to do it like so

let fruit = ["banana", "orange", "apple"];
fruit.splice(2, 0, "cat"); //cat in position 2 of the fruit array
