How does `json_last_error()` compare to using `try...catch` blocks for JSON handling?

Both `json_last_error()` and `try...catch` blocks can handle JSON errors, but they approach it differently. `json_last_error()` is a post-processing mechanism; you check for errors *after* the JSON operation. `try...catch` allows you to directly handle exceptions that might be thrown during JSON operations. `try...catch` generally provides more structured exception handling but may require changes to the code to anticipate potential exceptions. `json_last_error()` is simpler for basic error checking.
