JavaScript Essential

The JavaScript Essential course requires prior knowledge and skills corresponding to the JavaScript Starter course. In this course, you will study the semantics and key concepts of JavaScript in detail. Over 18 lessons, you will master the core principles of using JavaScript for building user interfaces and creating scripts that utilize object-oriented techniques and functional programming approaches. This course serves as a strong foundation for further learning of JavaScript-based libraries and frameworks. The last two sessions are dedicated entirely to hands-on practice to reinforce the acquired knowledge. Successfully completing this course will make it much easier for you to understand and start using frameworks like Angular or libraries like React.
• Working with the DOM
• Event handling
• Object-oriented programming: classes and inheritance
• Advanced function concepts: context, lexical scope, closures
• Client-side data storage
• Working with asynchronous code
• Network requests
Each lesson includes a homework assignment to reinforce the material and explore additional ways to apply the learned concepts.
