From 13723f267eb87f8c28ef0769cdf7e233b971326e Mon Sep 17 00:00:00 2001 From: Luke Edwards Date: Wed, 29 May 2024 16:16:27 -0700 Subject: feat: Add `Deno.exitCode` API (#23609) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commits adds the ability to set a would-be exit code for the Deno process without forcing an immediate exit, through the new `Deno.exitCode` API. - **Implements `Deno.exitCode` getter and setter**: Adds support for setting and retrieving a would-be exit code via `Deno.exitCode`. This allows for asynchronous cleanup before process termination without immediately exiting. - **Ensures type safety**: The setter for `Deno.exitCode` validates that the provided value is a number, throwing a TypeError if not, to ensure that only valid exit codes are set.
