Var Fun Facts Add Fun Fact

The `var` keyword in JavaScript allows for variable hoisting, meaning variables declared with `var` can be accessed before their declaration, but their value will be `undefined` until the line of declaration is reached.

Using the `var` keyword allows for the creation of global variables, even if declared inside a function, if no `var`, `let`, or `const` is used, promoting potential global scope pollution.
