This is the 18th in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!
Day 18
Today we are going to look at the 11th most popular addon on Ember Observer: ember-composable-helpers.

What It Does
The ember-composable-helper addon provides composable helpers for Ember apps, which allows for more declarative templating.
Now, the first time I read that sentence, I thought, "huh what?" so I want to break it down a little more.
This addon provides helpers. Useful helpers (like filter-by, repeat, and group-by, to name a few. These helpers can be used together (imagine using group-by in conjunction with filter-by…go ahead, imagine it, I'll wait…).
The declarative bit means that we're telling our template what we want to do, succinctly; ember-composable-helpers tells our app how to do it, saving us time and increasing our productivity.
Why I Like It
I think this addon is the bee's knees. It allows me to write code in the way I wish I could always write code! I love being able to say "here's what I want done, please." I'd rather not have to think too much about the "how", especially not every.single.time. I write code. The team that worked on this addon is known for producing useful addons, too, and I trust their work. Once again, strong community conventions come through for the benefit of all!
Even better, the fantastic team at EmberMap has a video about this addon if you want to learn more!
Do you use this addon? Or one like it? We'd love to hear about Ember addons that bring you joy!
