Challenge

Write a function of type String -> Integer. The input may or may not be a valid JSON string. If it is valid, the resulting JavaScript value is expected to be an object, but may not be. If it is an object, it is expected to have a foo property whose value is expected to be an object, but may not be. This value is expected to have a bar property which is expected to be an object with a baz property whose value is expected to be an array of strings. Each of these strings is expected to be a hex representation of an integer (e.g. 0xFF). If every element of the array meets this expectation, the

Motivation

• expression-oriented programming one of the great advances of FP
• expressions plug together like legos, making more malleable programming experience in-the-small

Examples

Write in an expression-oriented style, scoping variables as locally as possible:
