Objects and Functions in JavaScript

Object

• An object in JavaScript is used to store related data and information in one place.

  • An object stores data using key and value pairs.

Example:

let student = {
name: "Anandhi",
age: 21,
course: "Computer Science"
};

console.log(student.name);

Output:

Anandhi

Function

• A function is a block of code used to perform a specific task.

• We can create a function once and use it many times.

Example:

function greet() {
console.log("Hello");
}

greet();

OutputL:

Hello

Simple Difference :

• Object → Stores data.

• Function → Performs a task.
