Is It Correct? 🤔
A quiz needs to know if the player got it right or wrong! Let's learn how to check. ✅❌
console.log('Let us check some answers! 🤔')The Equals Check ⚖️
To compare two things we use === (three equal signs). It asks: are these the SAME? ⚖️
console.log(5 === 5)
console.log(5 === 8)True and False 🟢🔴
The computer answers with true 🟢 or false 🔴. That's how it tells right from wrong!
let correct = 7
let guess = 7
console.log(guess === correct)Check a Math Answer ➕
Let's see if a guess matches the real answer to 3 + 4! ➕
let answer = 3 + 4
let guess = 7
console.log('Did they get it right?', guess === answer)Using IF 🚦
With if we can do something special when the answer is correct! 🚦
let answer = 6
let guess = 6
if (guess === answer) {
console.log('Correct! 🎉')
}IF and ELSE 🔀
else tells the computer what to do when the answer is WRONG. 🔀
let answer = 10
let guess = 4
if (guess === answer) {
console.log('Correct! 🎉')
} else {
console.log('Oops, try again! ❌')
}Show the Right Answer 💡
When players are wrong, it's kind to show them the right answer! 💡
let answer = 12
let guess = 9
if (guess === answer) {
console.log('Correct! 🎉')
} else {
console.log('Nope! The answer was', answer)
}Check Many Answers 📋
We can check more than one question, one after another! 📋
let g1 = 4
let g2 = 9
console.log('Q1 right?', g1 === 4)
console.log('Q2 right?', g2 === 10)Make a Checker Function 🛠️
A function is a reusable helper. Let's build a checker we can use again and again! 🛠️
function check(guess, answer) {
if (guess === answer) {
console.log('Correct! 🎉')
} else {
console.log('Wrong! ❌')
}
}
check(5, 5)
check(3, 8)Watch Out for Type! 🧐
The number 7 and the text '7' are NOT the same to a computer. === checks both value AND type! 🧐
console.log(7 === 7)
console.log(7 === '7')Full Answer Check 🎮
Here is a complete answer check for one quiz question! 🎮
let answer = 6 + 6
let guess = 12
if (guess === answer) {
console.log('You got it! ⭐')
} else {
console.log('Almost! It was', answer)
