How to reference an Obj by a key inside of it in JS

Question

Lets say I have an array of objects:

inventory = [{name:'milk',price:4},{name:'apple',price:2}]

How could I reference the entire object that contains inventory.name = 'milk' or inventory.price = 4?

I need to reference it in order to return its index inside of the outer array.

Answer 1

There are several ways, but the first is:

const obj = inventory.find(object => object.name === "milk" || object.price === 4)

or you can use findIndex

Answer 2

Seems like you are looking for Array#findIndex :

const index = inventory.findIndex(item => item.name === 'milk');

Or use Array#find if you want the actual object.
