Try Catch Finally - Learn Data Science with Travis

Try-Catch-Finally

The try-catch-finally construct is a fundamental error-handling mechanism in programming, particularly in languages like JavaScript and Java. It allows developers to manage exceptions gracefully, ensuring that a program can continue running even when unexpected errors occur. The “try” block contains code that may throw an error, while the “catch” block handles the error if it arises, allowing for custom error responses. The “finally” block, which is optional, executes after the try and catch blocks, regardless of whether an error occurred, making it ideal for cleanup tasks. This structure enhances code robustness and user experience.
