running the code

[OmerHaj]

I ran the code and got this error message, [nodemon] app crashed - waiting for file changes before starting
I don't know if there was an output at all, and if any where Cani find the new cleaned file

[OmerHaj]

tried it again, no response at a ll. 'npm run dev:' didn't do anything

[OmerHaj]

I ran npm test got this
● Validation Error:

Test environment jest-environment-jsdom cannot be found. Make sure the testEnvironment configuration option points to an existing node module.

Configuration Documentation:

As of Jest 28 "jest-environment-jsdom" is no longer shipped by default, make sure to install it separately.
