I want to get all name from the array of data. Is there any way to do it without using an iterator?

const data = [
    {name: 'Rushabh', age: 22},
    {name: 'Bonny', age: 24}
]

console.log(Object.values(data));

    you can always do `data.map(obj => obj.name)` Not sure whether this counts as "using an iterator" or not though. (Any array is technically an iterator.) – Robin Zigmond Mar 07 '19 at 12:24
  • I know but is there any default method to do this thing? – Rushabh Shah Mar 07 '19 at 12:25
  • please add the wanted result. – Nina Scholz Mar 07 '19 at 12:26

  • not to be picky, but the question, whether or not it makes sense, was to **not** use an iterator. **Why?** doesn't matter at this point. Well, without **iterating** you would need to know how many items are in the array before hand, since you, again, are not **iterating**. Therefore, ```data[0].name``` and ```data[1].name``` are your two choices here. There have been solutions propsoed, but they **all** use **iteration**. yes, **map** is an iteration – gkelly Mar 07 '19 at 12:46

For getting only a single property, you need to map this property directly.

const
    data = [{ name: 'Rushabh', age: 22 }, { name: 'Bonny', age: 24 }],
    result = data.map(({ name }) => name); // get only name

console.log(result);

Try this:

const data = [
    {name: 'Rushabh', age: 22},
    {name: 'Bonny', age: 24}
]
const names = data.map(({name}) => name)
console.log(names);

the names will include the list of names.

Without some kind of iterator you can not do that. You can use map() with short hand property.

const data = [
    {name: 'Rushabh', age: 22},
    {name: 'Bonny', age: 24}
]
const name = data.map(({name}) => name);
console.log(name);

Use Array.map() and extract the name property:

const data = [
    {name: 'Rushabh', age: 22},
    {name: 'Bonny', age: 24}
]

console.log(data.map(x => x.name));

If you are using JQuery, do this:

const data = [
    {name: 'Rushabh', age: 22},
    {name: 'Bonny', age: 24}
] 
var names = $.map( data, function(item, key) { return item.name; } );
// names : ['Rushabh', 'Bonny']
