Get value of a key from a dictionary array JavaScript

Question

so in Javascript I have an array structured like this:

car = [{id: "1", brand: "Opel"}, {id: "2", brand: "Haima"},{id: "3", brand: "Toyota"}]

How can I get the values of all the brands only.

It depends on what you want to do with it. 1. A simple solution if you just want to log it to console car.forEach(car => console.log(car.brand)); Iterate over your car object with forEach. 2. If you want to collect it in an array for further manipulation const brands = car.map(car => car.brand); Map returns a new array of brand in that case. — gr4viton, Sep 27 '18 at 20:10

This should help:

const car = [{id: "1", brand: "Opel"}, {id: "2", brand: "Haima"},{id: "3", brand: "Toyota"}];

const brands = car.map(({ brand }) => brand);

you could also write car.map( o => o.brand) to save some letters – Martin Godzina Sep 27 '18 at 20:06

You can use array map to return all brands. Look at the following use of map.

car.map(o => o.brand)
