How does the 'this' keyword work in JavaScript?

Can you explain how the 'this' keyword works in JavaScript?

Sure! In JavaScript, 'this' refers to the context in which a function is called. It can vary depending on how the function is invoked.

What are the different contexts in which 'this' can be used?

'This' can be used in several contexts: global context, object methods, constructor functions, and arrow functions. Each context affects what 'this' refers to.

Can you give me an example of 'this' in an object method?

Absolutely! In an object method, 'this' refers to the object itself. For example:

const person = {
  name: 'Alice',
  greet: function() {
    console.log('Hello, ' + this.name);
  }
};

person.greet(); // Output: Hello, Alice
