Freezing Collections: A Guide

## Direct Answer
To freeze a collection, you need to prevent items from changing or being added/deleted. This is usually done by using the `Object.freeze()` method in JavaScript or by setting the collection to read-only in other programming languages.

## Step-by-Step Guide
Here’s how to freeze a collection in JavaScript:
1. Create a new collection or select an existing one.
2. Use the `Object.freeze()` method to freeze the collection: `Object.freeze(collection)`.
3. Verify that the collection is frozen by checking its `isFrozen` property or by trying to add, delete, or modify items.
