Cause: The value assigned to a variable does not match its declared type.
Solution: Check the variable’s type and ensure the assigned value is compatible.

3. Error: “Division by zero”

Cause: Attempting to divide a number by zero.
Solution: Add a check to ensure the divisor is not zero before performing the division.

Cause: The file path provided does not exist or is incorrect.
Solution: Verify the file path and ensure the file exists.

5. Error: “Unexpected token”

Cause: A syntax error in the code.
Solution: Review the code around the reported line for syntax errors.

6. Performance Issues

Cause: Inefficient code or excessive resource usage.
Solution: Optimize your code, avoid unnecessary computations, and use built-in libraries effectively.

Troubleshooting Tips

Check the Documentation: Many issues can be resolved by referring to the Language Reference or other sections of the documentation.
