About This Free Course
JavaScript es6 is the language of the internet. Learning it has allowed many front and backend web developers to get jobs. Yet JavaScript’s newest features can be confusing and hard to understand.
In this course you will learn to deeply understand how newer JavaScript language features work under-the-hood, such as:
Block Scoping (let and const)
Templates
Classes
Arrow Functions
Symbols
Iterators and Iterables
Default Parameters
Rest and Spread
ES6 and beyond refers to features added to the JavaScript language in ES6 and ES Next. These features often will make your coding life easier, and are used by modern JavaScript frameworks, like React, Vue, Angular, and more.
As always, these topics will be covered with the focus on my core philosophy: "Don't Imitate, Understand". You won't try to learn by imitating the code I'm writing, but rather by deeply understanding how these language features work inside JavaScript engines. Deeply understanding means you will not only write better code, but also find it much easier to debug problems.
This course’s goal, then, is to help you have a deep understanding of JavaScript’s newest features. Through analysis of the inner working of the JavaScript engine, you can write code more confidentially and fix problems others find difficult.
It’s time for you to deeply understand advanced JavaScript concepts!
Happy coding!
Who Should Take This Course
"Master Modern JavaScript ES6 features Certification" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on DeelCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
