What is the typical block structure used to catch and handle errors or exceptions thrown in JavaScript?

Errors or exceptions thrown in JavaScript are typically caught and handled using the `try...catch...finally` statement. Code that might throw an error is placed within the `try` block. If an error occurs, execution immediately jumps to the `catch` block, which receives the thrown error object as an argument. The optional `finally` block executes regardless of whether an error was thrown or caught. Example: `try { operationThatMightFail(); } catch (error) { console.error('An error occurred:', error.message); } finally { console.log('Cleanup complete.'); }`
