//! 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.
