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

May be too late, but javascript array has two methods some and every method that returns a boolean and can help you achieve this.

I think some would be most appropriate for what you intend to achieve.

vendors.some( vendor => vendor['Name'] !== 'Magenic' )

Some validates that any of the objects in the array satisfies the given condition.

vendors.every( vendor => vendor['Name'] !== 'Magenic' )

Every validates that all the objects in the array satisfies the given condition.
