How to determine if Javascript array contains an object with an attribute that equals a given value?

Question

I have an array like

vendors = [{
    Name: \'Magenic\',
    ID: \'ABC\'
  },
  {
    Name: \'Microsoft\',
    ID: \'DEF\'
  } // and so on... 
];
         


        

Answer 1

Alternatively you can do:

const find = (key, needle) => return !!~vendors.findIndex(v => (v[key] === needle));
