How to remove an item from array Typescript-CodePudding

I am quite new to Typescript so apologises if it is a simple answer.

I'm looking to remove the end item from an array.

const arr = [];

array consist of 3 classes:

{class1,class2,class3}

if .push is to input, what is to remove?

Thank you.

Answer found here (Link) by Darren z:

 arr.splice(-1)

GitHub Copilot will give you the answer :)

class class1 {}
class class2 {}
class class3 {}

const arr = [class1, class2, class3];

// remove the second item from arr
arr.splice(1, 1);

// remove class3 from arr by value
arr.splice(arr.indexOf(class3), 1);
