7272Line by line, this reads as follows:

7474- `Person` is a data type with one constructor, also called `Person`
7575 - The `Person` constructor takes an object with two properties, `name` which is a `String`, and `age` which is a `Number`
76−- The `itoa` function is written in Javascript, and takes a `Number` and returns a `String`
76+- The `numberToString` function is written in Javascript, and converts a `Number` to its `String` representation
7777- The `showPerson` function takes a `Person` and returns a `String`
7878- `showPerson` works by case analysis on its argument `p`, first matching the constructor `Person` and then using string concatenation and object accessors to return its result.
