TypeScript: Extend package types

// When a package doesn't have any types, we can silence TS with
import * as someLibrary from "some-library"

// And extend some types if we want better type safety
declare module "some-library" {
  export function missingFunctionDeclaration(): {
 x: number

	# Automatically uses the package manager of current directory
	# Just type "start" or any other scripts fo your package.json file

	p() {
	if [[ -f bun.lockb ]]; then
	command bun "$@"
	elif [[ -f pnpm-lock.yaml ]]; then
	command pnpm "$@"
	elif [[ -f yarn.lock ]]; then
	command yarn "$@"
