De-structuring ReScript type data (using pattern matching)

ReScript version: bs-platform@8.4.2

Suppose we have the following type:

type person = Person(string, int);

We can use this type as follows:

let joe = Person("Joe", 23);
let jim = Person("Jim", 31);

When we have variables like this, we can use pattern matching to extract the values:

let Person(name1, age1) = joe;
let Person(name2, age2) = jim;

Js.log2(name1, age1);
Js.log2(name2, age2);

// "Joe" 23
// "Jim" 31
