That's not a server side js issue. That's a React issue.
NodeJs on backend works perfectly fine and predictably.
With React things get a little confusing mainly because there is a huge ecosystem around react and everything can be another thing in different setups. (Like React Native vs NextJs vs React with Electron etc)
Once again tho, that is a react specific issue.
Oh! Interesting. Similar in Angular, Vue and other JS stacks or just React?
React specifically has the largest, most confusing and most diverse ecosystem. It's not entirely unique, but due to it's ecosystem's size it has some problems that are unique among it's peers. And even without the size. just like every other framework (no, it's not a library despite claiming to be one) it has unique problems stemming from the nature of how it's designed and/or implemented
