Node.js Interview Workbook: 100 Questions with Model Answers, Follow-ups and Drills

The only Node.js workbook you will need.

Node.js interviews don't stop at the definition. The interviewer asks a follow-up, then asks you to tie it to something you've built. This workbook prepares you for all three.

What's inside

• 100 questions covering every concept interviewers draw from
• A model answer for each, covering the tradeoff and not just the definition
• The follow-up an interviewer is likely to ask next
• A drill for each question that you answer from your own work, in fillable boxes inside the PDF
• A concept map at the front showing all twelve areas at a glance
• Three levels: 22 Foundation, 56 Intermediate, 22 Senior
• A coverage table mapping every concept to its question

The twelve sections

Fundamentals · Event loop · Async patterns · Modules and packages · Events, buffers and streams · Files and system · Networking · Processes and concurrency · Errors and debugging · Performance · Security · Tooling and deployment
