Bool

The bool type in Risor is a simple wrapper of the Go bool type.

All underlying object types in Risor implement the object.Object interface, which includes IsTruthy() and Equals(other) methods. It's good to keep this in mind since object "truthiness" can be leveraged in conditional statements.

>>> bool(0)
false
>>> bool(5)
true
>>> bool([])
false
>>> bool([1,2,3])
true
>>> if 5 { print("5 is truthy") }
5 is truthy
>>> 5 == 5.0
true
>>> [1,2] == [1,2]
true
>>> [1,2] != [1,2]
false
>>> false == false
true

bool(x)

Returns true or false according to the given objects "truthiness". Container types including lists, maps, sets, and strings evaluate to false when empty and true otherwise. Iterators are truthy when there are more items remaining to iterate over. Objects of other types are generally always considered to be truthy.
