I love zed, but boy do they like cramming in a bunch of annoying features.
There is still an open issue to fix the buggy auto-indent behavior.
Also, I can't get the damn thing to work with Makefiles, so I still use Sublime for that.
It's taken me a while to track down how to disable some of them, so here are my current settings:

| I've inserted newlines after 99 and 89, which seem to be very common bytes. | |

How do you convert an object to a string?
It started out simple enough:
var s = obj.toString();
Ooops. But wait. What if an object has a toString key inside of it?

| // Single function that implements A-Star pathfinding algorithm in ~75 lines of code | |

| // (why use a huge library..?) | |

| // Parameters: | |
| // solid array of booleans (of size width * height) that determine if a tile is solid | |
| // width width of the map | |
| // height height of the map |
