Coding Challenge: Rewriting Function with Better Types

Problem statement

We’ve added some imperfect TypeScript types to the function below, which takes two arguments. We’ve discovered that status can only have the values SUCCESS and FAILED and that scores are always numbers. The function below allows many illegal parameter types, such as showResult('fake', 'fake'), to compile when they shouldn’t. Our task in this challenge is to rewrite this function with better types.

function showResult(status: string, score: any) {
    if (status === 'SUCCESS' && score === 5) {
        console.log('Great, you got the highest possible score');
    } else if (status === 'SUCCESS') {
        console.log(`Nice, you got ${score}`);
    } else if (status === 'FAILED') {
        console.log('Sorry you failed');
    }
}
showResult('fake', 'fake');
