JavaScript Interview Preparation – Multiple Choice Questions to Ace It

Why JavaScript Interviews Require More Than Just Theory

JavaScript interviews today go beyond just knowing syntax. Recruiters test how well you understand the language, how you solve real problems, and how quickly you can think under pressure.

One of the best ways to prepare is by practicing JavaScript multiple-choice questions (MCQs). They help reinforce concepts, identify weak spots, and build confidence for the big day.

At JavaScript Exam, you can practice real interview-level MCQs with unlimited attempts and instant feedback.

  • ✅ Simulate Real Interview Conditions: Time-based quizzes build mental endurance.
  • ✅ Understand Core Topics: Like scopes, closures, async/await, and DOM manipulation.
  • ✅ Learn by Doing: Immediate feedback helps correct misconceptions on the spot.
  • ✅ Unlimited Practice: Retake tests until you feel interview-ready.

  • B. == checks type and value
