When you're using a library like chess.js for a project, do you take a moment to look at the code behind its functions, such as `.fen()` that provides the current state of the chessboard in FEN format? It seems like checking the implementation could help you understand whether it recalculates the board state or updates it incrementally after each move. Do you ever have these kinds of thoughts? How useful has it been for you to review the code of packages you use?

For smaller packages, I look out for security vulnerabilities and check for any odd network calls. I've noticed that glaring issues can often pop up during a manual review that automated tools might miss.
I usually check the recent commits to make sure the package hasn’t been compromised. Performance issues often reveal themselves during debugging or through flame graphs, which is pretty helpful.
Absolutely! The commit history and issue reports can give you a good idea about the package's reliability.
Honestly, I try not to use too many packages unless absolutely necessary. I usually rely on proven libraries, but when I do need something, I make sure to vet it properly to avoid issues later on.
I get that! It can be tough, especially when deadlines loom and someone else’s package is the only way forward.
In production, I definitely keep an eye on the code! Given how many packages have been exploited lately, I check for odd unicode characters and try to build safer local versions of common libraries.
You seem pretty intense about this! Who even uses some of the more obscure packages?
When the documentation is lacking, looking directly at the function definitions and parameters is often the only way to really grasp what can be done. It definitely pays off to dive into the code sometimes!
Do you actually study the docs? I tend to just check the code for lesser-known packages, especially if the docs are vague.
Yeah, tools like npm audit are great, but doing a manual scan can help catch those sneaky risks.
