💅 Bug with "unused else branch"

[maelp]

Environment information

I've got this code (sorry it's a bit long, didn't want to edit it for now) which I use as a small script with a "hacky" argument parser, which expects something like `./myscript someArgs -- someCommand someArgs`

and this it stops parsing args when it spots "--", but `biome` is telling me that the "else" clause is unused, although I'm pretty sure it is used... not sure why?


#!/usr/bin/env -S pnpm tsx

/**
 * Environment Variable Loader
 *
 * This module can be used in two ways:
 *
 * 1. As a preload script with -r flag:
 *    tsx -r '@workspace/config/env-loader' src/index.ts
 *    (Requires ENV_LOADER_PACKAGES env var as a comma-separated list of packages)
 *
 * 2. As a CLI tool:
 *    tsx env-loader -p package1 -p package2 -v KEY=VALUE -v ANOTHER=VALUE -- command args
 *
 * It loads environment variables from the TypeScript config
 * rather than from .env files, allowing for a single source of truth.
 *
 * The loader will always load the root ENV, then each specified package in order.
 * If a variable is defined in multiple places, it will exit with an error.

Not a bug; actually the else is not necessary.

The following code:

if (foo) {
  doSomething();
  break;
} else if (bar) {
  doSomething();
}

is equivalent to:

if (foo) {
  doSomething();
  break;
}

if (bar) {
  doSomething();
}
