Hoisting in JavaScript is a behavioral characteristic of the language where variable and function declarations are moved to the top of their containing scope during the compilation phase, before the actual execution of the code.
Hoisting affects both variable and function declarations, but not their assignments or initializations. It means that while the declarations are hoisted, the assignments or initializations remain in their original position.
