javascript object array contains 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`)
}

Example 3: check if property has value in array javascript

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