How to open the localhost 3000 project in the browser that I am doing in React?
I started the project yesterday and opened it with npm start.
It is no longer open today.

when i set npx create-react-app nameProject >
i chose project name "flowerbook"
now path to package.json'npm changed from \React_LarisaGrigoras\package.json'npm
to: React_LarisaGrigoras\flowerbook\package.json'npm
How to change path and run the project in the browser?

Answer 1

Removed the folder in the middle and the issue was resolved.
But I didn’t understand why set the project name when running npx create-react-app nameProject,
since this folder name is not saved, and then it turns into a problem ?!
