medium📝 Debug Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Understand local and export interaction
Declaring 'local VAR=123' limits VAR to the function scope. Exporting it inside the function exports it only in that shell instance.Step 2: Check effect outside function
After function ends, local VAR is destroyed. Export does not make it available outside the function's shell environment.Final Answer:
VAR is local and not exported outside the function -> Option AQuick Check:
Local variables cannot be exported outside function scope [OK]
Quick Trick: Exporting local vars inside function doesn't export globally [OK]
Common Mistakes:
MISTAKES- Expecting exported local variable to persist outside function
- Thinking export causes syntax error here
- Confusing local and global scopes
