Need simply clarify what’s hoisting?
What about closures?
I’ll make clarify you what’s variable declaration, initialization and project which are all-together referred to as Variable Lifecycle Phases.
We may also focus on this course on the Variables Utilization Tips:

Additionally, you will get a number of sensible workout routines the place you will want to use achieve data about completely different variables, hoisting, scopes and closures.
All workout routines and code samples can be found as Git repository.
Hope to see you onboard!
