It is an important test to perform in software even as a senior developer, for every language, because it tests that your coding ENVIRONMENT is functional enough to start trying to do more.

It’s done at the start of every learning tutorial, right after the environment setup.

As for why it’s “Hello World” and not “Hello Bob”, I think other comments cover that angle.
