To find intersection between a Object and array

Question

I'm beginner to javascript.

How to find intersection between a array and object in javascript.

Lets take:

   var use = [{name:'jony'}, {name: 'raja'}, {name: 'papy'}];

And array as:

   var now = ['jony', 'raja', 'singh'];

Now how can I get result as

   var result = ['jony', 'raja'];

Answer 1

var result = use.filter(function(e) {
    return now.indexOf(e.name) > -1;
}).map(function(e) { return e.name; });

console.log(result);  // ["jony", "raja"]
