Error handling is a critical aspect of any application. This section provides a comprehensive guide on how to effectively manage errors in our documentation.
Common Error Types
Syntax Errors: These occur when the code is not written correctly. For example, missing a semicolon at the end of a statement.
Runtime Errors: These happen during the execution of the program. For instance, dividing by zero or accessing an undefined variable.
Logical Errors: These occur when the code runs without any errors but produces incorrect results. They are often harder to debug.
Error Handling Best Practices
Use try-catch Blocks: This allows you to catch and handle exceptions gracefully.
- Example:
try { // code that might throw an exception } catch (Exception e) { // handle the exception }
- Example:
Log Errors: Always log errors for future reference. This helps in debugging and tracking down issues.

Provide User-Friendly Error Messages: Avoid exposing technical details to the end-user. Instead, provide clear and concise messages that guide them on how to resolve the issue.
Handle Errors Early: It's better to handle errors early in the development process rather than waiting until the end.
Use Exception Handling Libraries: Depending on the programming language, there are various libraries available to help with error handling.

By following these best practices, you can ensure that your application handles errors effectively and provides a better user experience.
