Local Scope

Variables declared inside a JavaScript function are LOCAL to that function.

Example

// code here can NOT use carName

function myFunction() {
  let carName = “Volvo”;
  // code here CAN use carName
}

// code here can NOT use carName
Local variables have function scope, meaning they can only be accessed within the function where they are declared.

Since local variables are only accessible within their respective functions, you can use the same variable name in different functions.

Local variables are created when a function is called and are deleted once the function finishes executing.
