What is the purpose of `try...catch` blocks within a `.then()` callback of a Promise?

While `.catch()` is the primary way to handle Promise rejections, `try...catch` blocks can be used *within* the `.then()` callback to catch synchronous errors that might occur during the processing of the resolved value. This is useful for handling errors that aren't directly related to the asynchronous operation itself, but arise during the subsequent logic. Example: `myPromise.then(result => { try { // Process result } catch (error) { console.error('Error processing result:', error); } }).catch(err => { console.error('Promise rejection:', err); });`
