Working with Arrays and Objects for Data Management

Intermediate

🧺 Arrays & 🗂️ Objects in JavaScript

Arrays and objects are fundamental data structures in JavaScript, used to organize and manage collections of data.


📚 Arrays

Ordered lists, created with square brackets:

let fruits = ['Apple', 'Banana', 'Cherry'];
console.log(fruits[0]); // Output: Apple

🧾 Objects

Key-value pairs, created with curly braces:

let person = {
  firstName: 'John',
  lastName: 'Doe',
  age: 25
};
console.log(person.firstName); // Output: John

🔧 Manipulating these structures allows developers to handle complex datasets efficiently, such as processing user lists or product inventories.
