Working with Arrays and Objects for Data Management
🧺 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.
