Arrays
An array is an ordered collection data structure used to store multiple items sequentially.
01 How It Works
Think of a numbered row of storage bins.
Arrays allocate zero-indexed numerical slots automatically for each sequential element item.
example.js
const fruits = ["apple", "banana", "cherry"];1. Initialize using square brackets [].
2. Insert items separated by commas.
3. Access elements via index numbers.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
const scores = [90, 85, 92];
console.log(scores.length);Key Takeaway
Arrays maintain ordered lists of data items efficiently.
