how to handle deprecation messages from npm for create-react-app?

[arkapratimsarkar]

I'm creating new react project by npx create-react-app my-app. It works fine. but when i delete the node-modules folder and use npm install,(same thing as cloning from remote repo) i get a lot of deprecation message. I'm not adding anything extra and the project runs fine but why am I getting all this deprecation messages ? can i do something about it or it is upto maintainers of various modules ?

node -v = v14.16.1

npm -v = 7.11.2

deprecation message -

npm WARN deprecated [email protected]: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

I think, it is up to the React maintainers to remove or update the deprecated dependencies on which it depends on. This might have nothing to do with create-react-app.

now the interesting thing is some people are getting this warnings and some people are not. even though they are using same versions of node and npm. it was suppose to be fixed in v4 of create-react-app but it hasn't . example #9431 (comment)
