It is also funny to see a JS developer criticise the architecture of PHP arrays specifically.
It does hint that perhaps bearjaws is (lucky for them!) too young to remember the mess that incomplete implementation of array/object duality got the JS world into.
Right. Then you are too young (as a developer at least!) to remember. Except that Object.entries() is there to remind you. And two different for() enumeration syntaxes (for...in and for...of).
JS has an enormous amount of bad-design scar tissue.
I find it interesting that JS developers will forgive it all (global variables, iterables confusion, broken this handling, insane implicit number and int conversions, not to mention simple stuff like semicolon handling) and think PHP developers doing the same for theirs are inferior.
It's a classic example of fundamental attribution error.
