What are some common methods for functions in JavaScript?

In JavaScript, functions are first-class objects, meaning they can have methods. Common methods include .call(), .apply(), and .bind().

.call() and .apply() sound interesting. Can you explain the difference between them?

.call() invokes a function with a specified this value and arguments provided individually, while .apply() takes an array of arguments.

What about .bind()? How is it different from .call() and .apply()?

.bind() creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments.

Can you give me an example of using .bind()?

Sure! Here's an example:

function greet() {
  console.log(`Hello, ${this.name}`);
}

const person = { name: 'Alice' };
const greetAlice = greet.bind(person);
greetAlice(); // Output: Hello, Alice
