Proof that TypeScript's Type System is Turing Complete
type StringBool = "true"|"false";


interface AnyNumber { prev?: any, isZero: StringBool };
interface PositiveNumber { prev: any, isZero: "false" };

type IsZero<TNumber extends AnyNumber> = TNumber["isZero"];
type Next<TNumber extends AnyNumber> = { prev: TNumber, isZero: "false" };
type Prev<TNumber extends PositiveNumber> = TNumber["prev"];

Several methods to get a random positive or negative number
// Math.random() will give you a random decimal number between 0 and 1
// Just check if the number is greater than 0.5
// And apply -1 or 1 depending on the result
Math.random() < 0.5 ? -1 : 1;
// Math.random() will give you a random decimal number between 0 and 1
// Math.rand() of a Math.random() will give you an integer 0 or 1
// Use 0 or 1 as a result of a condition to use -1 or 1
Math.round(Math.random()) ? -1 : 1;
// /!\ NOTE : Can be used for any other values like 9 or 37 ; -2 or 2...
