JavaScript: Merge Objects inside an array

i have an array (0,…,n) and with several object. The array can be of any length.

array = {{name: alice, age: 18, hobby: dance}, {name:bob, age: 27, hobby: cars}, {name: chloe, age:45, hobby: painting}};

Now I want a new array. This new array should look like that:

new array = {alice, bob, chloe};

I can merge this objects with a for-loop. But is there a simple join or merge function which I can use?

Thanks

    Just use map 😉

    let array = [{name: alice, age: 18, hobby: dance}, {name:bob, age: 27, hobby: cars}, {name: chloe, age:45, hobby: painting}];

let result = array.map(i => i.name)

    I don’t quite understand what you mean.

    your origin array

    array = [{name: alice, age: 18, hobby: dance}, {name:bob, age: 27, hobby: cars}, {name: chloe, age:45, hobby: painting}];

    the new array you want get

    new array = [alice, bob, chloe];

    you can use

    array.map(o => ({ [o.name]: o }))

    Is this the answer you want?
