Arrow Functions
Recreate the last assignment, but this time create an arrow function called
percentageOfWorld3.
const percentageOfWorld3 = population => (population / 7900) * 100;
const percPortugal3 = percentageOfWorld3(10);
const percChina3 = percentageOfWorld3(1441);
const percUSA3 = percentageOfWorld3(332);
console.log(percPortugal3, percChina3, percUSA3);
