how can I retrieve specific property of an object of multiple objects [duplicate]

Question

I need help in getting values of specific property of an array of multiple objects I have an array like this:

[
    {
        "id": 1,
        "name": "skill 1"
    },
    {
        "id": 2,
        "name": "skill 2"
    },
    {
        "id": 3,
        "name": "skill 3"
    }]

and I want to get a string like this :

skill 1 - skill 2 - skill 3

Please read through How do I ask a good question? Your best bet here is to do your research, search for related topics on SO and elsewhere, and give it a go. If you get stuck and can't get unstuck after doing more research and searching, post a minimal reproducible example showing your attempt and say specifically where you're stuck. People will be glad to help. (not my downvote) — T.J. Crowder

Too trivial for a full answer myArray.map((v) => v.name).join(" - ") would do the trick. — spender

@DBS - Clunky, hard to read, easy to get wrong, and hard to debug. Outside functional programming with predefined, reusable reducer functions, reduce is just an overcomplicated loop. Use a loop instead. — T.J. Crowder

First step is to extract name. You can use map.

elements.map(x=>x.name)

Second step is to join it to one string using join

const result = elements.map(x=>x.name).join(' - ');
