The JavaScript engine first reads the code, and then runs it. The errors that occur on the reading phrase are called "parse-time" errors and are unrecoverable (from inside that code). That's because the engine can't understand the code. The JavaScript engine first reads the code, and then runs it.

So, `try..catch` can only handle errors that occur in the valid code. Such errors are called "runtime errors" or, sometimes, "exceptions". So, `try..catch` can only handle errors that occur in the valid code. Such errors are called "runtime errors" or, sometimes, "exceptions".

You can check by running the code with entering `35` into `prompt` -- it executes normally, `finally` after `try`. And then enter `-1` -- there will be an immediate error, an the execution will take `0ms`. Both measurements are done correctly.

In other words, the function may finish with `return` or `throw`, that doesn't matter. The `finally` clause executes in both cases. In other words, the function may finish with `return` or `throw`, that doesn't matter. The `finally` clause executes in both cases.
