In general, here's what you'll find in the course: - Modern JavaScript from the start: The JavaScript syntax changed over time - in this course, you'll learn the latest syntax from the start (you'll also learn about the old one though, so that you can work in ANY JS project) - ALL the Basics: Variables, constants, functions, how scripts are loaded etc - Arrays & Objects: We'll explore these very important data structures in great detail - Control Structures: Understand how to run code conditionally and in loops - A look behind the Scenes: How JavaScript engines work behind the scenes and what that means for us - Deep dives into Core Concepts: ALL the special things about JavaScript function, different syntaxes - Working with the DOM: How to manipulate web pages dynamically via JavaScript (including deep dives and different use-cases) - Events in JavaScript: Learn how to listen to a broad variety of events (e.g. drag & drop) and execute appropriate code - Classes & Object-oriented Programming: Learn how to work with classes, prototypes, the "this" keyword, constructor functions and much more - Asynchronous and Synchronous Programming: We'll explore callbacks, promises, async/ await and other important tools and language features to execute code correctly - Http Requests: Learn how to send Http requests via JavaScript - Tooling, Optimizations & Browser Support: Code splitting, producing small code and ensuring that scripts work in all browsers - this matters and hence is covered in great detail - Libraries & Frameworks: Learn about libraries like Axios or frameworks like React.js - why they matter and how to use them - Node.js: Whilst focusing on the browser-side for the majority of the course (because the syntax is the same), we'll also have a dedicated section on Node.js to learn all about that JS host environment - Security & Performance Optimizations: Of course security matters, so does performance - no surprise that both is covered in the course! - Automated Testing: Testing manually is hard work and can be unreliable - in this course you'll also get an introduction into automated testing What are the course prerequisites? - NO JavaScript knowledge is required - you'll learn it from scratch! - You also need NO programming experience other than basic web development knowledge (e.g. how the web works) - Basic HTML and CSS knowledge is recommended but not a must-have
