Method

In JavaScript, objects can have properties and methods. A method is simply "a function of the object".

Let's look at several examples of methods for handling strings (length, toUpperCase).

length, toUpperCase Method Examples

let name = 'banana';

// A method that returns the length of the string
console.log(name.length); // 6

// A method that converts the string to uppercase
console.log(name.toUpperCase()); // BANANA

These methods can be defined not only for primitive data types but also for user-defined objects.

2. Differences between Methods and Functions:

Function:

• A function is an independent block of code. It is a set of instructions that perform a specific task.
• Functions are not bound to any particular object.
• Function Example

  function greet() {
    console.log('Hello!');
  }
  greet(); // Hello!

Method:

• A method is a function defined as a property of an object.
• Methods are called within the context of the corresponding object and often access other properties of the object.
• Use the this keyword to refer to the object within a method. Here, this refers to the object that owns the method.
• Method Example

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