Pablo

length

The length property gives the number of elements currently in the collection. This is similar to the length property of a JavaScript array.

var collection = Pablo();
alert(collection.length); // 0

collection.add(Pablo.circle());
alert(collection.length); // 1

collection.add(Pablo.line());
alert(collection.length); // 2
