Your 2nd JavaScript Course: Advanced Concepts and Algorithms


About this course:

This is a JavaScript enhancement course, designed to help junior JavaScript developers gain a wider and deeper understanding of JavaScript.

If you want to take the leap from a junior JavaScript developer to a senior one, then you have found the right course.

What you will learn: 

You will learn ES6 new features like destructuring assignment, async/await, reflect, proxy, symbol, iterator, generator, etc.

Then you will learn the JavaScript object system and prototypal inheritance in the most detailed way. You will learn every methods the Object constructor has.

To completely understand how JavaScript works, you will learn advanced topics like thread, process, stack, queue, heap, task queue, event loop, recursion, deep and shallow object copy, etc.

To further boost your coding skills, you will also learn 8 sorting algorithmsbubble sorting, cocktail sorting, quick sorting, counting sorting, insertion sorting, bucket sorting, selection sorting and heap sorting.

You will also develop a proper understanding of linear and non-linear data structures, including array, linked list, binary search tree, max heap, min heap, etc.

What you will achieve:

After this course, you will develop a solid JavaScript knowledge base and most importantly, gain a deep understanding of how JavaScript works under the hood. These knowledge can help you create more efficient programs and succeed in job interviews.

If you need to learn JS frameworks like Vue, React, Angular, a solid knowledge foundation in JavaScript can tremendously accelerate your study.

Throughout the course, you will also learn how to answer questions that are frequently seen in job interviews.
