Understand different types of scopes?
Want easily explain what is hoisting?
What about closures?
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.
Hope to see you onboard!
