I'm working with Leaflet.js & Leaflet-Editable.js there are a lot places where I need to respond to clicks on, creation of, etc. different types of map features differently. This function allows me to eschew if,else,if,else blocks for these cases.

Example:

Before

if(is(L.Marker, feature)){
  setMarkerStyleActive(feature);
} else if(is(L.Polyline, feature)){
 setPolylineStyleActive(feature);

Why Is It Bad To Export Functions Exclusively For Testing?

ℹ️ Summary: Test the destination, not the route.

We have a module that doubles numbers. It does this by bit-shifting the supplied number once left.

// double.js

// exported to allow testing...
