1/**2 *3 * TruePromise is a an overhaul of the javascript class Promise. [Learn how to use Promises](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).4 *5 *6 * TruePromise is meant to be used with TypeScript.7 *8 * _TruePromise works with async/await syntax in a nodeJS environnement. â ï¸ Not tested in a commonJS environnement._9 *10 * - Do not throw error if not handled.11 * - Allow delayed calling of then/catch.12 * - Correctly type the value in reject cases.13 * - Rework of the static methods with better types.14 * - New timeout() static method.15 *16 * The main purpose of a Promise is to handle a script that can be accepted (resolved), or refused (rejected). For each case, it case send a value.17 * TruePromise is used the same way as javascript Promise. Some returned value may change in static methods.18 * All methods offer documentation while hovering them in your IDE. Most of them are taken from [Mozilla's Promise documentation](https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Global_Objects/Promise).19 */20export class TruePromise<ResolveValue = void, RejectValue = void> {21 // "pending": waiting for resolve or reject.
