JavaScript Hoisting With Examples | Hoisting In Javascript
Hoisting is a JavaScript mechanism that allows variable and function declarations to be moved to the top of their containing scope during the compilation phase before the code is actually executed. This means that regardless of where variables and functions are declared in the code, they are moved to the top of their scope.
Hoisting applies to both variable declarations (using the var keyword) and function declarations.
