IIFE

  • Immediately-invoked function expressions.

  • A design pattern used by most popular libraries to place all library code inside of a local scope.

  • No global property is created for the function (anonymous function expression).

  • All of the properties created inside of the function expression are scoped locally.

  • Encapsulation, preserve the global namespace as any variables declared within the function body will be local to the closure but will still live throughout runtime.

  • Benefits:

    • Local scoping.
