I want to display the array but only with name and age
const users = [{name: 'john', age: 20, instrument: 'guitar'}, {name: 'mary', age: 20, instrument: 'piano'}];
let userList = users.map(users => {name: users.name, users.instrument })
console.log(userList);didn't work. I'm missing a return somewhere right?
You should wrap the object statement in each iteration with ().
Also, I prefer using Destructuring assignment:
const users = [{name: 'john', age: 20, instrument: 'guitar'}, {name: 'mary', age: 20, instrument: 'piano'}];
var new_users = users.map(({name,instrument}) => ({name, instrument}));
console.log(new_users);You just need to wrap object inside ()
const users = [{name: 'john', age: 20, instrument: 'guitar'}, {name: 'mary', age: 20, instrument: 'piano'}];
var result = users.map(user => ({ name: user.name, instrument: user.instrument }));
console.log(result)= when setting users.users but use user.' after 'guitar() around the object in the mapping function as it will be treated as arrow function if forgottenIn the end it should look like this:
const users = [{name: 'john', age: 20, instrument: 'guitar'}, {name: 'mary', age: 20, instrument: 'piano'}];
const mapped = users.map(user => ({name: user.name, instrument: user.instrument}));
console.log(mapped);
