Most examples for reduce show you how to take an array of numbers and reduce them to a simple sum. Reduce is a great tool for this, but it can do so much more. It is a powerful tool, and essential to functional programming techniques.

This course will dig deep into the Array#reduce in JavaScript and give you a solid understanding to start using it today.

    What did you like about this course?

    The author carefully and thoroughly explained the topic in such a way that it was easy to understand and remember. Another differentiator - he didn't rely on a prepared script. This made the presentations feel conversational rather than other egghead talks where the authors seem to read through some prepared text as fast as they can. Overall the talks where a nice combination of brevity w/just enough depth of detail. Nice Job!

    Thank you for finally helping me understand reduce by providing examples other than summing an array! It is also helpful to know when to use it. I was really stuck before I watched your videos!
