Hoisting in Javascript #shorts

Hoisting is a behavior in JavaScript where variable and function declarations are moved to the top of their scope. This means that variables and functions can be used before they are declared in the code.

In JavaScript, variable declarations are hoisted to the top of their scope, but their assignments are not. This means that if you try to access a variable before it’s been declared, it will return undefined.

Function declarations are also hoisted in JavaScript. This means that you can call a function before it’s been declared in the code.
