Can someone enlighten me why it is so important to keep sane the output of this function , to such extent, that it requires a separate library code to cover this case? It looks like some people can't stand without wiping asses of everyone who writes absurdly broken & non-functional code, to make sure it keeps being absurd and broken even after you upgrade the javascript version. :D

[@Lord_zeel]

@@igorstasenko9183 Because there might be some website somewhere that checks for that output to determine something important, and if the message changes by even one character it won't match and everything breaks. It might even be a TEST that expects that output, and changing it would cause all the tests to fail which could cost someone time and money figuring out what changed. So instead, there spec specifies the message, and the polyfill makes sure the message matches the spec even if it's a silly thing like that. There are dozens of other messages that are way more important than that one, but the author of the polyfill isn't going to decide which ones seem important and which ones don't, they are just going to make sure they are all to-spec just in case. That is, after all, the point of the polyfill. If we didn't care that all the edge cases were covered, we would just write out own `Array.prototype.at = function...` replacement. It's not as if that's a complicated function after all! But we want anything like a polyfill to be extremely reliable, that's why we use them. So they need to cover EVERYTHING in the spec.

"When to write an DSL?" If the DSL solves a Problem AND it is your core business. Good Examples: Dockerfile uses a DSL. The DSL is a tight reflection of how Docker builds the file and the dsl removes a ton of noise in comparison to YAML. More complex requirements can be solved trough RUN Commands and args etc. In comparison saltstack and ansible are using YAML with jinja. Any DSL would be so massiv complex that it wouldnt add any value. In contrast Config languages for e.g. webservers most of the time are not adding great value (see apache,nginx vs. traefik)

So here is the future - 1. Someone probably Evan You, comes up with removing bloated dependencies that are not needed for transpiled code. 2. It is a success, but then people have opinions and 10 other debloat-transpiler-code. 3. 1-10+ new dependencies for this new package added to your code base. 4. Someone now comes and makes same thing in Rust claiming 80% improvement on speed to debloat-transpiled code. Repeat same cycle to detect ES6+ code in ES5 code.

ES5 is buried under enough abstractions that moving away from it creates enough resistance and doesn't have enough need for some to bother.

So if a manager fires an employee, that can only be a bad decision, if the absence of that employee can be directly traced to some damage. The savings in salary can always be traced to the decision to fire them. An increase in salary is always an increase in cost and thus at least questionable.

This isn't C though.. Array could just as well be implemented as a linked list for all you know. Negative indexing as a shorthand for "from the end" is a very common language construct, and also reduces noise for the common action picking the last (few) elements of an array. And yes, the whole point of the method is to support negative indices. So if you're not expecting negative values you shouldn't use it.

@@leeroyjenkins0 linked lists aren’t circular so the first node doesn’t have a pointer set to te end. Otherwise it’s a circular buffer. And it wouldn’t be an array. An array is a contiguous piece of memory the size of the number of elements you specified. You can defend it but it’s a syntactically inconsistent. If you want such a behavior write your own method that does it. In a proper language this shouldn’t have a place. Or at least do it for example list[::-1] which is at least more explicit. It I hate it, all this syntactic sugar is making a language unnecessarily big and inconsistent. Not a fan.

@@CallousCoder nope, this is JavaScript. An Array is an object where you can only use numerical properties. Doing array[N] is simply setting or getting a property of the object. You're free to handle that however you want as the implementer of the interpreter. "let x = []; x[15] = 1; x[0] === undefined; x[20] = undefined; x.length === 16; " it's all valid JS despite not setting a length when creating the Array. JS doesn't expose memory addresses, there's no concept of contiguous sections of memories you can request. You can implement an Array any number of ways, even though typically it's mostly just a C-style array of some kind.. Yes you can implement it in your own util.. but why would you? You can implement indexing yourself too, why don't you just do actual pointer arithmetics "int* x = malloc(...); int x1 = *(x + sizeof(int));" instead of the bloat that is "int x1 = x[1];"?

@@leeroyjenkins0 all for pointer arithmetic 🤣 But seriously indexing is fine of course. It’s the extra method .at() that already is a bit too much added functionality to me because you can index already. And then at(-1) is syntactically inconsistent. Because it would suggest base pointer -1. Perhaps in a syntactical purist 😉I love language to be tiny and not have all that frivolity that also adds weird inconsistencies that require you to know how the method is I implemented. I also know now, why I hardly use JavaScript 😂Although C++ also has its horrible extra ease of us abstractions. Mee should just go back to C or assembly 😉 But thanks for the enlightening JavaScript deep dive.

There is no 'hoisting' in JS Specification. It is just inheritance... -___-

??? That's not true.

@@thekwoka4707 I cant proof You that there is no such term, but You can try to find it yourself in ECMAScript Specs... I glad for your reaction and will be waiting for your results. It is blowed my view on JS.

@@thekwoka4707 I can't prove You that something doesn't exist, but You can try to take a look for it in ECMAScript Specs. It is really exciting to take a look on JS by this new angle. I will wait for your search results here. Maybe You can prove me wrong (for the first time I will loose this argument).

Yes, supporting ES5 is a waste of resources, but It sounds like the author forgot that advertisements and embedded content exists, instead assuming every piece of JS returned by a site is in its control.
