A curated collection of hundreds of JavaScript interview questions with answers for Frontend Engineer interviews, maintained by GreatFrontEnd and updated for 2026. Questions are organized by importance and difficulty, covering core concepts like hoisting, the event loop, and `this`.

Use cases

• prepare for a frontend engineer interview
• study javascript interview questions and answers
• review javascript concepts like hoisting and the event loop
• find commonly asked react and javascript interview questions
• refresh javascript knowledge before an interview
• practice quiz-style frontend interview questions by difficulty

When to choose

• you are preparing for a front end or JavaScript developer interview
• you want curated, high-quality answers written by ex-FAANG interviewers
• you need a quick refresher on core JavaScript concepts
• you want questions organized by difficulty and importance

When to avoid

• you need a runnable library or tool rather than study material
• you want backend or non-JavaScript interview prep
• you need hands-on coding practice with automated test cases, which requires the paid GreatFrontEnd platform
• you expect to contribute content changes, since this is a read-only public mirror
