Conditionals
π¨βπΌ Nice work! You've built a grade calculator with branching logic.
π¦ Notice how the
else if chain works: once a condition is true, the rest are
skipped. That's why we can write score >= 80 for Bβwe already know it's not= 90 because that check came first.
An alternative approach uses early returns in functions (we'll cover this
soon):
function getGrade(score: number): string {
if (score >= 90) return 'A'
if (score >= 80) return 'B'
if (score >= 70) return 'C'
if (score >= 60) return 'D'
return 'F'
}
This pattern is often cleaner for this type of logic.
