best way to check in an array if any of object has that key code example

Example 1: angular list contains property

vendors.filter(function(vendor){ return vendor.Name === "Magenic" })

Example 2: javascript array contains object

// Works in all browsers
if (array.index(object) !== -1) {
  console.log(`my object is in my array`)
}

// ES7 :
if(array.includes(oject)) {
  console.log(`my object is in my array`)
}
