Functional Programming — The Examples Series

I’ve been integrating some functional programming techniques into my day-to-day. I’ve been aware of them for a pretty long while (e.g. I’ve been using underscore.js for three years(!) I think). It wasn’t until the recent Fluent conference that I finally got off my mental butt to try and really use them.

I’ve been slow to pick up stuff because I never came across an great real world examples that would amke it obvious. Fluent got me the fire in my belly, so to speak. This information-rich but not super well produced YouTub video (especially the early bits) bridged the gap for me in terms of “map,” “filter” and “reduce.”

The rubber hit the road when I tried and it’s coming together for me. I’m intending to write a series of very short little examples of where I’ve used it and hopefully that will be useful to someone.

Here they are (to be updated over time):

• Simple Filter
• Parsing a Flattened Two Dimensional Array Into a “Real” Two Dimensional Array
• Populate an Array With Test Data (compare/contrast imperative with functional approach)
• Mixing Arrays and Non-Arrays Via the Ternary Operator
• Use Reduce to Get Unique Values From Array of Complex Objects
• Multiple Techniques to Get Unique Values From an Array of Complex Objects
• Use Reduce to Create a Formatted String
• Use Reduce to Return a Complex Object From Lookup Table Via Simple Key
• Double Your Objects With This One Weird Trick (or, Reduce Doesn’t Exactly Mean What I Thought It Did)

More to come!
