Else Statement

if (condition) {
  // Runs if condition is true
} else {
  // Runs if condition is false
}
 // Example:
const age = 15
 if (age >= 18) {
  console.log('You can vote!')
} else {
  console.log('Too young to vote')  // This runs
}

const password = 'secret123'
const input = 'wrongpass'
 if (input === password) {
  console.log('Access granted!')
} else {
  console.log('Wrong password!')  // This runs
}

const number = 7
 if (number % 2 === 0) {
  console.log(number + ' is even')
} else {
  console.log(number + ' is odd')  // This runs
}
 // % is the remainder operator
// Even numbers have no remainder when divided by 2

const temp = 65
 if (temp > 70) {
  console.log('Wear shorts!')
} else {
  console.log('Wear a jacket!')  // This runs
}

const score = 85
 if (score >= 60) {
  console.log('You passed!')  // Runs
}
 if (score < 60) {
  console.log('You failed')   // Doesn't run
}
 // Both conditions are checked even though only one can be true

const score = 85
 if (score >= 60) {
  console.log('You passed!')  // Runs
} else {
  console.log('You failed')
}
 // More efficient! Second check is skipped when first is true

const username = 'player1'
const loggedIn = false
 if (loggedIn) {
  console.log('Welcome back, ' + username + '!')
} else {
  console.log('Please log in')  // This runs
}

const itemsInStock = 0
 if (itemsInStock > 0) {
  console.log('Add to cart')
} else {
  console.log('Out of stock!')  // This runs
}

const playerHealth = 0
const enemyHealth = 50
 if (enemyHealth <= 0) {
  console.log('You won!')
} else {
  console.log('Keep fighting!')  // This runs
}
 if (playerHealth <= 0) {
  console.log('Game Over!')  // This also runs
} else {
  console.log('You survived!')
}

const total = 45
const hasCoupon = false
 if (hasCoupon) {
  const discount = total * 0.20
  console.log('Discount: $' + discount)
  console.log('Final price: $' + (total - discount))
} else {

  console.log('Total: $' + total)  // This runs
