The block that can execute code at the end of a try...catch statement, regardless of whether an exception was thrown, is the finally block. This block is specifically designed to run a set of statements after the try and catch blocks have completed execution.

When dealing with exceptions in JavaScript, the try block allows you to define a block of code where exceptions may occur. If an exception arises, the catch block will handle it. However, the finally block serves the purpose of executing code that must run regardless of the outcome—this includes both scenarios where an exception is thrown and where no exceptions occur.

This ensures that critical cleanup actions, like closing files or releasing resources, are always performed, safeguarding against potential resource leaks. For instance, if you are opening a database connection in the try block and want to ensure that it gets closed whether an error occurs or not, you would place the close operation in the finally block.
