I assume this is satire, but for those who might take this seriously, please avoid doing tricks like this.

You're doing so much extra work here. Creating many new arrays, running a bunch of extra function calls, creating extra closures, and really obfuscating code from the engine. This will tank performance.

This is the point at which people come back at me with something about "premature optimization" being bad. That's all well and good, but if you prematurely pessimize and let these patterns creep throughout your codebase, you end up with products that are significantly slower than they should be.

I've spent quite a while working on JS engines, and it always impresses me how much extra work exists in JS developers' code, seemingly for no real reason, and it's slowing down the entire internet. This doesn't appear to be better for the developer, the user, or any potential future maintainers.
