Deno fmt conflicting with Deno lint, when using IIFE

// before formating

// before formating

after formating with deno fmt, it adds an extra semicolon before the IIFE, but deno lint says Unnecessary semicolon. Remove the extra (and unnecessary) semi-colon deno-lint(no-extra-semi)...

How can I let my program keep running even if it receives SIGINT?

I succeeded to write a program to handle SIGINT using Deno.addSignalListener("SIGINT", ...) API, ~~but Deno always exits when it receives a SIGINT whether I put Deno.exit() inside the signal handler or not.~~ [Edit: It was my mistake. Deno keeps running if a signal handler was registered.] I just want my program to reload the configuration file instead of terminating when it receives SIGINT. Is there any way to do it?

I have a server side app I want to host in a specific region and I only want 1 instance of it running at a time, so deno deploy is not really right for this. Are there any other hosting services that are deno friendly?...

Update value by reference without duplicating the data

Im exploring the world of FFI, porting some C applications I have to TypeScript, with the help of Deno. Currently, I cannot think of an efficient way to update the value that a pointer is pointing to. For instance, in C I could do something like: ```c char *array = calloc(2, sizeof(char)); if (array == NULL) return 1; *(array) = "hello";...
