Callbacks in Action | Best Practices

When done correctly, callbacks are like a well-oiled machine. When done poorly, they're like a cat in a bathtub.

Callbacks are functions passed as arguments to other functions or methods. They allow for modular code and a more organized approach to problem-solving.

Why Bother with Callbacks?

Because callbacks are the unsung heroes of programming.

Callbacks enable code to be reusable, flexible, and adaptable. They let us write more maintainable, scalable, and readable code.

Types of Callbacks

The holy trinity of callbacks: callbacks by function, callbacks in action, and async callbacks.

Best Practices

Don't be a callback cowboy.

Use callbacks judiciously, and with caution. Only use them when necessary, and with clear purpose.

                // Example of a well-crafted callback
                function addToList(list) {
                    return list.push(1);
                }
                var list = [1, 2, 3];
                list.push(4, addToList(list));
