Does NodeJS respect Docker virtualization and resource limits?

It is known that some applications aren't aware of Linux kernel isolation and virtualization features such as cgroups. This includes system utils like top, free and ps, but also platforms like Java.

I've recently read an article which suggests that when running JVMs in Kubernetes, you should enforce manual limits on the Java heap size to avoid errors.

I cannot find anywhere whether this is also true for NodeJS. Do I need to implement something like above to set --max_old_space_size=XXX on my NodeJS application in Kubernetes?
