An array is a special variable that can store multiple values in a single place. Instead of creating many separate variables, arrays allow you to organize related data together.
For example, a list of student names, product prices, or scores can all be stored in arrays. This makes data easier to manage and process.
Arrays are one of the most important tools in JavaScript and are used in almost every real-world application.
Why Arrays Are Important
- They store multiple values in one variable
- They help organize data neatly
- They make programs easier to manage
- They work perfectly with loops
- They are used in almost every application
Without arrays, handling large amounts of data would be very difficult.
Here, three separate variables are used to store names. If you have 100 names, you would need 100 variables.
This is not practical, which is why arrays are used.
Now, all names are stored in a single array called names.
This makes the code cleaner and easier to manage.
This example shows how to access values from an array using index numbers. Arrays start counting from 0 in JavaScript.
By understanding arrays, students gain the ability to manage lists of data and build dynamic, data-driven applications.
