Text typed:

JavaScript is very flexible about the types of values it requires. We've seen this for booleans: when JavaScript expects a boolean value, you may supply a value of any type, and JavaScript will convert it as needed. Some values ("truthy" values) convert to true and others ("falsy" values) convert to false.
