Checkpoint: First Steps

Question 1 of 5

let total = "0";
total = total + 450;
total = total + 1220;
console.log(total);

• 1670
• "1670"
• NaN
• 04501220

Question 2 of 5

• Declare it with var so it works everywhere.
• Declare it with let count = 0; because the value has to change.
• Replace count++ with count = count + 1.
• Wrap the increment in parentheses: (count)++.

Question 3 of 5

• Compare with == instead of ===.
• Compare subtotal.toFixed(2) === 0.3.
• Store every amount as whole cents (integers), so 10 + 20 === 30 exactly.
• Call parseFloat(subtotal) before comparing.

Question 4 of 5

const label = "  Rent ";
const clean = label.trim().toLowerCase();
console.log(label.length, clean);

• 7 rent
• 4 rent
• 7 Rent
• 4 Rent

Question 5 of 5

• "Spent
  quot; + cents / 100 + " on " + item
• `Spent ${cents / 100} on ${item}`
• 'Spent ${(cents / 100).toFixed(2)} on ${item}'
• `Spent ${(cents / 100).toFixed(2)} on ${item}`
