Safe `Array.reduce()` when using PrototypeJS v1.6 and lower.
npm install array-reduce-prototypejs-fixPrototypeJS was a popular JS library many years ago. It extended and changed native objects. Which led to collisions with newer versions of browsers, if they implemented methods with the same names. This is the case of Array.reduce() (see native versus Prototype's implementation).
This, kids, is exactly why you should never touch native objects. And this is why PrototypeJS lost JavaScript libraries war and Jquery won.
Anyway, if you need to use Array.reduce() in a project that uses PrototypeJS v1.6 and lower (they removed it from v1.7), this module should help you. Since PrototypeJS replaced the original method, there's no way to get it back. We could replace the method with polyfill, but that would potentially break the code expecting PrototypeJS' method. So instead we create a new function. It checks for the presence of PrototypeJS. If it is there, it uses polyfill. Otherwise it uses native implementation.
Just remember that this should be a temporary fix. Real fix would be to get rid of PrototypeJS from your project. Or at least to upgrade it to v1.7.
Does exactly the same as native Array.reduce(), but is safe to use when PrototypeJS v1.6 or lower is present.
