Why .push is not a function?

I copy & paste the first part of this video, but my browser told me capitalizedFruit.push is not a function.

I googled but it said this error happen when it's applied to array element, it should be fine to be applied on array like this case. Why does this happen?

1 Answer

Are you invoking(calling) push function? You need to call push function.

Try it out:

let capitalizedFruit = [];

It should work!
