Sandbox (software development)

In software development, a sandbox is a safe area to test and experiment with code. Think of a sandbox like a playground - it's a contained area that allows you to explore and play without worrying about breaking something important. When you use a sandbox, you can safely try different things without the risk of affecting the rest of your system. This means you can practice coding and try out design ideas without having to worry so much about messing up your work.
