Is it ok that create a project on node@14+ but run it on node@12？

[KoreSamuel]

I hope to create a new project by the CRA, but the terminal notified me that the expected version >=14.
and from the Getting Started document

You’ll need to have Node >= 14 on your local development machine (but it’s not required on the server). You can use nvm (macOS/Linux) or nvm-windows to switch Node versions between different projects.

I can switch the node version between various projects, but in our production docker image, the nodejs version is 12.22.12.
so may I ask is it ok that create a project on node@14+ but run it on node@12？
or could you give me some advice to create a new project on node@12 please?
Thanks.
