Change some for ... in .. clauses to for ... of ... #230

luke-schleicher · 2021-12-09T18:56:35Z

Context: I am running a nodejs server that I was trying to integrate this library into.

However, our server uses some monkeypatched extensions of Arrays for convenience. Functions like first, last, pluck, etc (Array.prototype.first = function() {...})

When trying to integrate this library into my project, it failed on the call to init, because this code was iterating not only over the indices in the arrays (0, 1, 2, etc), but also the names of our extension (first, last, pluck, etc).

This obviously threw an error when it tried to call clause.op on a Function.

I'm sure there's opinions out there either way on the practice of monkeypatching a global object type like Array, but regardless this made it much harder to integrate launchdarkly because I had to go through and remove all our extensions from the code.

As far as I know, for ... of ... is the recommended method to iterate over arrays as well.

I've gone ahead and changed all the instances of for ... in ... that were preventing library initialization. There may be more for ... in ... that should be converted to for ... of ..., but I suppose half the purpose of this PR is to draw your attention to this issue and get a conversation going.

On the one hand, monkey-patching Array in particular is an uncommon practice that, as you say, there are some pretty strong opinions about. In fact I think it's safe to say that most people would consider it a bad practice; it has consequences that monkey-patching other classes would not, because JS developers are accustomed to the idea that other kinds of objects can have spurious properties that come from their prototypes (and would therefore always use either for...of or Object.hasOwnProperty to iterate named properties), but JS developers generally will assume that an ordinary array is just an array. So I would certainly be strongly against any library developer doing such a thing.

When an application developer does it, they can at least take responsibility for making sure their own code is safe. Your request here is for the library code to also be adjusted to tolerate this practice. I think, on the general principle of programming defensively against an unknown environment, that's probably reasonable for us to do— as long as we can enforce it via the linter to make sure we don't accidentally re-introduce unsafe usages, which I'm fairly sure is doable. However, we definitely cannot guarantee that the SDK will be resilient against monkey-patching of built-in JS types in general. It's too hard to anticipate every potential consequence. Probably the best we can do is to adjust the for usage.

Of course, even if the LaunchDarkly SDK is made to tolerate this, that doesn't mean it won't cause problems in any of the many other NPM packages you might be using, so I would still strongly recommend migrating away from this approach in the future.

There are definitely more for...in usages in other files that we'll need to update. So, rather than merging this PR, we'll make our own development branch for these changes. I'll leave this PR open in the meantime just to make it clear that it's being worked on, but I'll close it when we're getting ready to release the changes. Thanks for bringing it up.

@eli-darkly Thanks so much for the comments.

Definitely sympathetic to what you're saying about monkey-patching being a dangerous practice, as well as your comment about it being helpful for libraries to be defensive when practical.

Thanks for looking into this
