Add code tabs to fun-write-method-returns-function

[doehyunbaek]

With c875c65 I updated Gemfile.lock.

Is it needed or better not tracked in git? I assumed the former from the previous commits to the file and if i misunderstood it I'll revert and force push the change.

With 60a87c4, I updated code tab, per #2481.

I tested each code with 2.13.10 repl and 3.2.1 repl and tested the website with jekyll

Thank you very much @doehyunbaek for your help!

I just noticed one minor possible improvement.

[doehyunbaek]

I added the for attribute because of this mention and should it also be updated?

[doehyunbaek]

I rebased onto origin/main and force-pushed branch.

I am not sure about this version change for the bundler. Here we use 2.3.10:

docs.scala-lang/Dockerfile

Line 4 in 00302d7

RUN gem install bundler:2.3.10 jekyll

Can you give me a brief advice on when to commit Gemfile.lock file change? It seems always is not the option. So is it never? or for some portion of the lock file(e.g. except bundler version?

[doehyunbaek]

Updated with fc15ab3, would still appreciate your advice.

[julienrf]

The changes to the lockfile should always be committed, but the file should be generated with the right version of the bundler. Could you please make sure to have bundler 2.3.10 on your system, or to use the Docker approach to automatically use the correct version of the bundler?

[doehyunbaek]

I actually have bundler 2.3.10 installed at my local mac. Strange it changed the lockfile.

I will try to commit lockfile with correct bundler version as specified in Dockerfile and will use the Docker approach if I'm not able to do that.

Thank you for updating the PR. I don’t think the documentation should be updated, the advice explaining the possibility of adding the for property when that helps readability still applies.
