That was the best understanding of an Array method I had in just 10 minutes. Clear and thorough ! Thank you.

I studied Javascript for 1 year or more and never fully understood the Reduce method, just for basic things like sum, but this explanation was monstrous. Thank you Colt Steele

Another great use case for .reduce() is that you can use it to build up sequences of strings. If you think of code itself as just being a sequence of strings, then it's possible to use reduce to automate writing code. ☺️

When would you want to use this vs writing your own recursive function? They both act in a similar way and in the data structure course, a lot of the recursion examples were similar to these reduce ones

Reduce object section (8.04min): A weak comparison is made with the equality (==) operator where the "null" value is seen in the same way as an "undefined" value. If we use the strict equality comparison (===) we see that with "null" we have problems while with undefined we do not. I think it is always a good idea to use strinct equality comparisons instead of weak ones, also to avoid wasting time in debugging. I always follow you when I can Cold ;)

Thank you so much Colt! Love your courses on Udemy, you are one of the best teacher I ever encountered, would you consider do some tutorials for PHP? since I would like to be freelancing for website development, wordpress is still widely used... hope I can get some response from you, thanks!

Is second case doing .map() method? We can do the same with .map(), right? I heard that .reduce() wraps .filter() and . map() methods

My question is, why lot of people do not recommend using reduce. I saw lot of articles, even lint configuration when it yells when using reduce. What are your thoughts on this?
