decrementOneHundred.immutable.js
const oneHundred = 100; // <-- now a `const` instead of a `let`
const decrementOneHundred = x => oneHundred - x;
decrementOneHundred(20); // 80
// oneHundred = 80; <-- would be runtime error: "TypeError: Assignment to constant variable."
decrementOneHundred(20); // 80
