How to remove a property of an object in an array in javascript ?

Question

const menu =[
{ id:2,
title:"pizza",
discount : ["./food-img/discount15.png" , "./food-img/discount.png"]
}
]

I want to remove discount property just in this object , how can i do that ?

Answer 1

As I understand You want to get rid of key:value pair with key discount. Then I assume You’ll have to use delete operator:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete

So I’d guess it could look like:
delete menu[0].discount

Where 0 is obviously the index of this element.

You can also keep the discount key and just empty the discount array to keep the same look of all objects in the menu array if that’s what You’re aiming for
