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

As the OP has asked the question if the key exists or not.

A more elegant solution that will return boolean using ES6 reduce function can be

const magenicVendorExists =  vendors.reduce((accumulator, vendor) => (accumulator||vendor.Name === "Magenic"), false);

Note: The initial parameter of reduce is a false and if the array has the key it will return true.

Hope it helps for better and cleaner code implementation
