Note that the Object.keys() method has been available since ECMAScript 2015 or ES6, and the Object.values() and Object.entries() have been available since ECMAScript 2017.We want to talk about using JavaScript as an alternative to jQuery especially moving forward as rails 5.1 removes jQuery as a dependency by default you'll still probably use it in a lot of applications especially ones that need good backwards compatibility because jQuery was really introduced as a compatibility layer across your browsers because JavaScript operated very differently than it does today in modern browsers so with that said we're going to talk about some various different things like how do you do queries for elements on the page how do you add events how do you hide and show items just like you would do with jQuery and so on so let's dive into this and begin now the first most common thing you want to do often times is to grab items from the Dom and query for them so that you're going to interact with them in some way so take this example we have a notifications which is a wrapper around each of those notifications on the page so this is where we can grab and interact with all of those notifications so for example. To convert an object to an array you use one of three methods: Object.keys(), Object.values(), and Object.entries().
Summary: in this tutorial, you will learn how to convert an object to an array using Object’s methods.
