Understand JavaScript Engine phases and lifecycles of the "var", "let", "const". Scopes, hoisting, closures simplified.
Do you want to understand real difference between different types of variables in JavaScript?
Understand different types of scopes?
Want easily explain what is hoisting?
What about closures?
In this course I will dive deep into the JavaScript and explain you what happens under the hood when you declare any variable or function. You will understand what happens on the "Compilation" and "Execution" phases in JavaScript Engine.
I will make explain you what is variable declaration, initialization and assignment that are all-together called Variable Lifecycle Phases.
We will also focus in this course on the Variables Usage Guidelines:
Make Code clear and readable for others
Always declare variables before first usage
Always use "use strict" globally
Don't expose to the outer scopes local variables
You will also get several practical exercises where you will need to apply gain knowledge about different variables, hoisting, scopes and closures.
All exercises and code samples are available as Git repository.

Do you really want to understand and practice instead of sitting and watching long presentations or trying to code along without any clue what is happening behind the scenes?Join me in any of my courses and you will get real knowledge based on the deep understanding of every single topic.But who am I?My name is Bogdan Stashchuk and I teach...
doesn't feel like a good use of time. most of this could have been explained in 1 paragraph.
Perfect, informative, very useful.
Very nice course! Comprehensive course about var,let,const and hoisting. Thanks a lot for the course!
