Description
Do you want to understand the real difference between different types of variables in JavaScript?Understand different types of scopes? Want to easily explain what is hoisting?
What about closures?
In this course, I will dive deep into JavaScript and explain to 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 to you what is variable declaration, initialization, and assignment are altogether 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 the 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 a Git repository.
