// Needs Bun

import biome from './biome.json';

// Extracted from https://biomejs.dev/linter/rules/#recommended-rules
const recommended = (await Bun.file('./recommended.txt').text())
  .split('\n')
  .map((x: string) => x.trim())
  .filter(Boolean);

%GetOptimizationStatus return a set of bitwise flags instead of a single value, to access the value, you need to take the binary representation of the returned value. Now, for example, if 65 is returned, the binary representation is the following:

(65).toString(2).padStart(12, '0');
// 000001000001

Each binary digit acts as a boolean with the following meaning:

// Step 1: Define the Branded Type
type LowercaseString = string & { __brand: "LowercaseString" };

// Step 2: Type Guard Function
function toLowercaseString(s: string): LowercaseString {
    return s.toLowerCase() as LowercaseString;
}

// Step 3: Override Type Definitions
type RemoveToLowerCase<T> = Omit<T, "toLowerCase">;

DarkGL

declare const __brand: unique symbol
type Brand<B> = { [__brand]: B }
export type Branded<T, B> = T & Brand<B>

/**
 * Branded type for a person's age, should belong to the interval [0, 125] (inclusive)
 **/
type Age = Branded<number, "Age">;
