Show usage of bind.
When a function is used as a callback, this is lost. bind() method has to be used to prevent losing this. The bind() method solves this problem.
Preserving Context in Callbacks: When you pass a function as a callback to another function, the context (`this` value) might change. By using `bind`, you can ensure that the callback function maintains the desired context. This is especially important when working with asynchronous operations like event listeners or AJAX requests.
Creating Partial Functions: You can use `bind` to create partial functions by pre-filling some of the arguments of a function. This is helpful when you have a function that accepts multiple arguments and you want to fix some of them to specific values.
Currying Functions: Currying involves breaking down a function that takes multiple arguments into a series of functions that each take a single argument. You can use `bind` to achieve currying by progressively binding arguments.
Creating Event Handlers: When you create event handlers for DOM elements, you can use `bind` to ensure that the correct context is maintained when the event is triggered.
