It's rather a broad question, but there's three main things you want to know about objects and classes in JS: 1). Everything is an object - this famously includes JS's first class functions. 2). There are object literals. var myObject = { "foo": 123, "bar": [4,5

1. Not everybody realises this but you can actually write in an object oriented manor using JavaScript. This works regardless of whether jQuery is in place or not. An interesting feature of JS is that functions can be variables and these functions can have sub variables and sub functions, and so on. For example: The above code would alert ‘variable’ when run. Notice how parentFunction has a childFunction within it and that the childFunction is able to use variables that have been defined in the parent. Nice! It’s worth commenting that if you were to try and access the protectedValue variable outside of the parent Function then this would not be allowed.

1. Selecting elements. Selecting one or several DOM elements to do something with is one of the most basic elements of jQuery. The equivalent to $() or jQuery() in JavaScript is querySelector() or querySelectorAll(), which, just like with jQuery, you can call with a CSS selector.
2. Working with events. There’s a myriad of ways to listen to events in jQuery, but whether you’re using .on(), .bind(), .live or .click(), you’ll make do with the JavaScript equivalent .addEventListener
3. Styling elements. If you’re calling .css() on an element to change its inline CSS with jQuery, you’d use .style in JavaScript and assign values to its different properties to achieve the same effect
4. Document ready. If you need to wait for the DOM to fully load before e.g. attaching events to objects in the DOM, you’d typically use $(document).ready() or the common short-hand $() in jQuery.
5. Working with classes. You can easily access and work with classes through the classList property to toggle, replace, add, and remove classes: // With jQuery // Add, remove, and the toggle the "focus" class $(".box").addClass("focus"); $(".box").removeClass("focus"); $(".box").toggleClass("focus"); // Without jQuery // Add, remove, and the toggle the "focus" class var box = document.querySelector(".box"); box.classList.add("focus"); box.classList.remove("focus"); box.classList.toggle("focus");
6. Network requests with .get() or .ajax() fetch() lets you create network requests in a similar fashion to jQuery’s ajax() and get() methods. fetch() takes a URL as an argument, and returns a Promise that you can use to handle the response
7. Creating elements. If you want to dynamically create an element in JavaScript to add to the DOM you can call createElement() on document and pass it a tag name to indicate what element you want to create
8. Updating the DOM. If you’re looking to change the text of an element or to add new elements to the DOM chances are that you’ve come across innerHTML(), but using it may expose you to cross-site scripting (XSS) attacks.
9. In summary. This is by no means a comprehensive guide to any of the native JavaScript methods utilized here, but I hope it’s been helpful a guide if you’re looking to move away from jQuery.

1. Object-Oriented Programming (OOP) is a programming model that is based on the concept of classes and objects. As opposed to procedural programming where the focus is on writing procedures or functions that perform operations on the data, in object-oriented programming the focus is on the creations of objects which contain both data and functions together. Object-oriented programming has several advantages over conventional or procedural style of programming. The most important ones are listed below: 1. It provides a clear modular structure for the programs. 2. It helps you adhere to the "don't repeat yourself" (DRY) principle, and thus make your code much easier to maintain, modify and debug. 3. It makes it possible to create more complicated behavior with less code and shorter development time and high degree of reusability. The following sections will describe how classes and objects work in PHP.
