Node.js - Debugging and Profiling
What will be the output in Chrome DevTools console if you run Node.js with node --inspect app.js and set a breakpoint inside a function that logs 'Hello'?
A'Hello' logs immediately without pausing
BNo output appears because debugging is disabled
CNode.js crashes due to missing --inspect-brk flag
DExecution pauses at the breakpoint allowing inspection; 'Hello' logs after resume
Step-by-Step Solution
Solution:
Step 1: Understand behavior of --inspect with breakpoints
--inspect enables debugging; breakpoints pause execution at specified lines.
Step 2: Predict output when breakpoint is hit
Execution pauses at breakpoint; after resuming, 'Hello' logs to console.
Final Answer:
Execution pauses at the breakpoint allowing inspection; 'Hello' logs after resume -> Option D
Quick Check:
Breakpoint pauses execution = Execution pauses at the breakpoint allowing inspection; 'Hello' logs after resume [OK]
Quick Trick:Breakpoints pause code; logs appear after resuming [OK]
Common Mistakes:
Thinking logs appear before pause
Assuming crash without --inspect-brk
Believing debugging is off without flags
