Jquery how to find an Object by attribute in an Array

Question

Given I have an array of \"purpose\" objects:

//array of purpose objects:
var purposeObjects = [
    {purpose: \"daily\"},
    {purpose: \"weekly\"},
    {pu         


        

Answer 1

No need for jQuery.

JavaScript arrays have a find method, so you can achieve that in one line:

array.find((o) => { return o[propertyName] === propertyValue }

Example

const purposeObjects = [
    {purpose: "daily"},
    {purpose: "weekly"},
    {purpose: "monthly"}
];

purposeObjects.find((o) => { return o["purpose"] === "weekly" }

// output -> {purpose: "weekly"}

If you need IE compatibility, import this polyfill in your code.
