Bound arrow =>

Learn Bound arrow => in CoffeeScript with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

Bound arrow => is an atomic CoffeeScript topic inside Functions. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Bound arrow => changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

coffeescript-02-02-bound-arrow.coffee
coffeescript Try It Live 
class Counter
  count: 0
  tick: => @count += 1
Edge case / engineering note

Change the key input in this CoffeeScript example and predict the result first; the named construct should be the reason the behavior changes.
