This isn't a concern unless you're tuning performance and the loop is a bottleneck. forEach can be slower (if the JS engine doesn't inline the function body), but not to the extent that you need to structure your code around it.

Yeah, I agree with that. Which is why I mentioned performance sensitive stuff like WebGL.

Personally I use the functional methods whenever I can, but the original quote I re-posted indicates that the author thinks that for-loops should always be replaced with their functional equivalents, and I was just pointing out that this is not universally a good idea yet.

Yeah, I agree - just adding a caveat to your caveat.

Personally I found the whole article very skippable. None of it is necessarily terrible advice, but everything is overstated, and said without really explaining why its advice better than the alternatives.
