What does it mean this function removeItem = (item) => { _.remove(this.items, item); };inside this class? And anyone knows why there is an underscore before the method?

Modern PHP
All these features have been discussed countless times in "new release" threads and such, but I don't think I ever asked public opinion on the "spaceship" operator, so I want to raise the question this time. I always ignored it as a feature that I personally don't need, but somebody else does, so ok, whatever.
You see, I actually don't think I ever used usort in about 10 years (or how long is it since anonymous functions were introduced). Instead, in all of my projects there is an implementation of https://underscorejs.org/#sortBy
The difference is that the callback maps the value to something that is already sortable using other native PHP functions, like an integer or a string. I find it way more intuitive than writing these function($a, $b) {/* try to remember which of [-1,0,1] it is supposed to return /} abominations. So as a solutions to remembering "which of [-1,0,1] should it be" I'd expect just natively implementing in C sane* sortBy function to replace this pre-historic PHP bullshit. But whatever, it's a matter of taste…
…Or so I thought until now. Now that I think about it, I see [-1,0,1] callback as something really fucked up. PHP usort (and basically all PL ordering functions I know) can order only linear sequences, i.e. it returns an ordered list. Not even a lattice. Basically this means real numbers (or, more comfortable to use in a PL: strings). And with [-1,0,1] I can define whatever the fuck I want. There's nothing to stop me from implementing "paper/scissors/rock" (or even something much more convoluted) in it, and I have to idea how usort will behave then. That doesn't sound good.
So I'd like somebody to persuade me that I personally need [-1,0,1] comparison model for some use case I apparently never encountered. The only reason I can think of why [-1,0,1] might be better is performance (or RAM, actually), but I don't accept is as a valid argument: somehow even my non-optimal sortBy PHP implementation always turns out to be enough, and if I really should worry about sorting performance, PHP probably isn't the right language for my use-case anyway.

Lenses and Partial-application - Going functional one step at a time
The code illustrated in this post is not recommended for use in production but the concepts most certainly are. Libraries like lodash and underscope provide many tried and tested, production-ready functions, some from the FP camp, that can simplify your code and make it easier to create reusable code.
