The Complete 2025 JavaScript MasterClass: Beginner Friendly

If you're looking to learn pure JavaScript and become a Frontend Developer / JavaScript Developer, this course is for you. You'll learn complete JavaScript from scratch, including data types, variables, functions, classes and basic principles that will help you navigate other programming languages in the future. You'll learn how to interact with the DOM, modify the HTML elements using JavaScript and even set up events, so that when you click, for example, a button, a custom function that you'll write gets executed.

Also, you'll learn how to create and structure your projects using modern design patterns that are an industry standard. But most importantly, you'll have a better understanding of how vanilla JavaScript works, so that when you decide in the future to pursue frameworks like React and Angular, you'll know exactly how and where to fix your bugs and mistakes. Course Walkthrough:We'll start off with the basics of JavaScript, like what data types there are, how to declare and use variables, and write functions without repeating code for efficiency.

Then, we'll move on to DOM Manipulation, how to directly change HTML attributes of elements through JavaScript, and we'll use events to pass data into our code from the UI. After that, we'll continue to Object Oriented Programming, we'll cover what are classes and how to create objects from them which we'll use to store the data we receive from the UI. Next, we'll move on to Asynchronous JavaScript, how to make HTTP calls to a server and retrieve data without interrupting the UI.

We'll then move on to Error Handling, using that for handling any errors we might encounter while performing actions like retrieving data from HTTP calls, also Regular Expressions for form validation such as a valid email address or password, full name, etc. and we'll conclude this section with Local Storage, how to store data that we need to persist in the browser's storage. In the next section, we'll cover Anonymous and Lambda Functions, how to use them as callback functions and how they work.
