I get some warnings and errors messages when try to create a react.js app using the command npx creat-react-app
here is the terminal output containing the errors I get. also I wanna specify that when the react.js app is created regardless of these errors it's actually working. but I'm afraid of that if there is something missing. Node.js and all of the required tools are installed as well.

Seems like you don't have git installed. Install git if you want cra to initialize a git repository. If you don't plan on using git, you should just ignore the error.

This thread points out that you can use npm install --no-optional to prevent warning from happening.

npm i -g typescript
should solve the problem

I'm starting a brand new project with react-js, after installing the project with npm, I get high severity vulnerabilities, how can I fix these vulnerabilities? would it cause any problems?
when I run the command npm start everything seems to work just fine.

I believe there is nothing to worry about according to gaearon
"This is not a real “vulnerability” in the context of Create React App because it produces static bundles. So it can’t possibly affect you in any way.
The false positive warnings are unfortunate."
EDIT: For me currently is says there are now 0 vulnerabilities
