Yes, very useful... Combine this technique with the design pattern for simplifying conditional by using polymorphism. I'm eager to use this approach.

What about if/return statements?

function run(action) {
if (action === 'created') return afterCreate( );
if (action === 'updated') return afterUpdate( );
If (action === 'destroyed') return afterDestroy( );
}

First, this is not a map it's an object. Recreating a map on every call is bad performance wise and memory wise. You could use a
switch(action) {
case 'created': createdAction(); break;
...
}
Thats no memory overhead no computation overhead, single hash calculation. Optimized compilation. Not a single else.
