Why a Comprehensive JavaScript Exam is Essential for Every Developer

Whether you're taking your first steps into the world of JavaScript or you're a seasoned professional aiming for a senior role, continuous assessment of your skills is vital. JavaScript exams aren't just about getting a certificate; they're about:

  • Validating your knowledge: Confirming your understanding of core concepts and advanced patterns.
  • Identifying knowledge gaps: Pinpointing areas where you need more study or practice.
  • Building confidence: Proving to yourself and potential employers that you're proficient.
  • Staying updated: JavaScript evolves rapidly, and regular testing helps you keep pace.

Sample JavaScript Exam Question (All Levels)

Let's look at an example that might appear in a JavaScript exam, suitable for both beginners and those with more experience:

What will be logged to the console?

const arr = [1, 2, 3];
for (var i = 0; i < arr.length; i++) {
  setTimeout(function() {
    console.log('Index: ' + i + ', Value: ' + arr[i]);
  }, 100);
}

Options:

  • A. Index: 0, Value: 1; Index: 1, Value: 2; Index: 2, Value: 3
  • B. Index: 3, Value: undefined (printed 3 times)
  • C. Index: 0, Value: undefined; Index: 1, Value: undefined; Index: 2, Value: undefined
  • D. ✅ Index: 3, Value: undefined; Index: 3, Value: undefined; Index: 3, Value: undefined

Explanation: This question tests understanding of var scope and asynchronous execution. The for loop completes its execution before the setTimeout callbacks run. By the time the callbacks execute, the i variable (which is var-scoped and thus function-scoped/globally-scoped) has already incremented to 3. At i=3, arr[3] is undefined. To fix this, one would typically use let for the loop variable, which introduces block-scoping.
