Eli5 – How are computer viruses created without destroying the creator’s computer first?

Question

I’ve always wondered how computer viruses are made. If someone creates a virus on their own computer, wouldn’t it infect and potentially destroy their system first before it’s spread to others?

Answer 1

You can create it on a different OS (Linux) and use a virtual machine (windows) in a sandbox environment to test it out.
