Hoisting is a behavior in JavaScript where variable and function declarations are moved to the top of their containing scope during compilation.
Variable declarations are hoisted to the top of their scope, but not their assignments.
Function declarations are fully hoisted, meaning they can be called before they are declared.
Hoisting can lead to unexpected behavior if not understood properly.
Callbacks are functions passed as arguments to another function to be executed later.
Callbacks are commonly used in asynchronous programming to handle events or responses.
They can be used to perform actions after a certain task is completed.
Callbacks can also be used for error handling or to pass data between functions.
