methods

morse.encode(obj)

Encodes and returns a given string or array

morse.decode(obj, dichotomic)

Decodes and returns a string or array

dichotomic defaults to false. If passed true, it will use a tree-based approach to decode the string or array. If false, a basic iteration of the map is used.

The dichotomic approach looks like this:

The implementation does not include spaces right now, so it fails its test. However, it is otherwise accurate.

morse.decode(
  morse.encode('Hello, world.'),
  true
);
// HELLO,5WORLD.

attributes
