Check if value exists in Array object Javascript or Angular

Question

I want to check if value exist in array object, example:

I have this array:

[
    {id: 1, name: \'foo\'},
    {id: 2, name: \'bar\'},
    {id: 3, nam         


        

Answer 1

You can use Array.prototype.some

var a = [
   {id: 1, name: 'foo'},
   {id: 2, name: 'bar'},
   {id: 3, name: 'test'}
];        

var isPresent = a.some(function(el){ return el.id === 2});
console.log(isPresent);
