How to access specific value from a nested array within an object array?

Question

I am trying to get a specific field value from a nested array within an object array. I\'m assuming I\'d use map, but every time I use it in this way I get two empty arrays nest

Answer 1

A quick function to return an item with the desired property and value of that property :

data = [{id:1,name:'Bob',hobbies:['a','b']},{id:2,name:'Alice',hobbies:['c','d']}];

function getPerson(property,value){
 for(var i=0;i

And a test :

console.log(getPerson('name','Bob'));
console.log(getPerson('name','Bob').hobbies);
