What is the role of the Try, Catch, and Finally Blocks in JavaScript ?
Last Updated :

The try
, catch
, and finally
blocks are used for error handling in JavaScript. The try
block contains the code that might throw an exception. If an exception occurs, it is caught by the catch
block, which contains the error-handling logic. The finally
block, if present, is executed regardless of whether an exception is thrown or not. This structure ensures graceful error handling and cleanup operations, enhancing the robustness of JavaScript code.
Example:
try {
// Code that may throw an error
} catch (error)
{
// Handle the error
} finally
{
// Code to be executed regardless of an error
}
