Predict the Output of a Basic For Loop with Condition

Analyze the given JavaScript code snippet involving a for loop and conditional statements, then determine the output printed to the console.

Challenge prompt

Consider the following JavaScript code: function printNumbers() { let result = ''; for (let i = 1; i <= 5; i++) { if (i % 2 === 0) { result += i + '-even '; } else { result += i + '-odd '; } } console.log(result.trim()); } What will be printed when printNumbers() is called?

Guidance

• Pay attention to how the loop iterates from 1 to 5.
• Understand the condition checking if the number is even or odd.
• Note how the result string is built during each iteration.

Hints

• Remember the modulus operator (%) returns the remainder after division.
• Even numbers have a remainder of 0 when divided by 2.
• The trim() method removes trailing spaces from the result string.

Starter code

function printNumbers() {
  let result = '';
  for (let i = 1; i <= 5; i++) {
    if (i % 2 === 0) {
      result += i + '-even ';
    } else {
      result += i + '-odd ';
    }
  }
  console.log(result.trim());
}

printNumbers();

Expected output

1-odd 2-even 3-odd 4-even 5-odd
