This upgrades TypeScript to 5.0.2, but does not have ES decorator support because swc does not support that yet.

//! There are many types of errors in Deno:
|
|
//! - AnyError: a generic wrapper that can encapsulate any type of error.
|
|
//! - JsError: a container for the error message and stack trace for exceptions
|
|
//! thrown in JavaScript code. We use this to pretty-print stack traces.
|
|
//! - Diagnostic: these are errors that originate in TypeScript's compiler.
|
|
//! They're similar to JsError, in that they have line numbers. But
|
|
//! Diagnostics are compile-time type errors, whereas JsErrors are runtime
|
|
//! exceptions.
