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!
