Code example has redundant `else` block

[sangupta]

The else block in the code example below is redundant - as it is immediately preceded by a return statement. Code sample is as under:

The code block is available on this page: https://eloquentjavascript.net/3rd_edition/00_intro.html

There are other occurrences where the same pattern is used. I can help send a PR if needed.

You are right in this particular instance, but Eloquent Javascript is a beginner's book, so I think it is sensible to spell out the full example. Without memoization this just a toy implementation anyway.

[sangupta]

Agreed. Just a thought around adding a comment to the code to let reader's know that they may skip it out.

Yeah this is intentional. Sure it's technically redundant, but it's entirely harmless and makes the code easier to scan. You'll see more code like that throughout the book.
