It's important for JavaScript
Developers to have a deep understanding of the language's complex concepts and inner workings
In addition, a deep understanding of how JavaScript works helps you effectively use modern frameworks such as
and write better and more maintainable code.
React
Vue
Angular
Knowledge of OOP, asynchrony, Event Loop, modularity, and data structures allows you to create productive and scalable applications.
Who this course is for
You will learn how to write complex and structured code using advanced JavaScript concepts and create a project for your portfolio.
Beginning developers with knowledge of JS, HTML and CSS basics:
You'll understand the inner workings of JavaScript, such as Event Loop and modularity, to write more efficient code.
For those who want to structure knowledge or learn how JS works under the hood:
You'll master the key concepts behind React, Vue, and Angular for a solid start with frameworks.
For those who want to deepen their knowledge before moving on to frameworks:
You'll learn how to solve complex problems, optimize code, and apply advanced programming techniques to real-world projects.
For those who want to become a confident Middle developer:
You are only required to have a basic understanding of JavaScript, HTML and CSS to successfully complete the course
