How do you bind a JavaScript method to a specific object?

• A. By using the `apply()` method
• B. By using the `bind()` method
• C. By using the `call()` method
• D. By using the `link()` method

Answer: (B)

Binding a JavaScript method to a specific object is effectively accomplished through the use of the `bind()` method. When you invoke `bind()` on a function, it returns a new function where the `this` keyword is set to the specified object. This means that whenever the new function is called, it will use the provided object as its context. For instance, if you have an object with properties and methods, and you want to ensure a method always references the object it belongs to, you can bind the method to that object. This is particularly useful in scenarios where the method may be passed around as a callback or used in event handlers, where it might lose its original context. The `bind()` method is versatile and can also accept additional parameters, which will be passed to the bound function whenever it is called. This capability allows for significant flexibility in managing method contexts in your JavaScript code. The other methods mentioned don't serve the purpose of permanently binding a method to a specific object in the same manner. The `apply()` and `call()` methods are used to invoke functions immediately with a specified context, rather than creating a new function. The `link()` method, on the other hand, is not related to binding functions in JavaScript
