Async/Await

Provides a helper function for handling asynchronous operations using async/await syntax in environments that do not natively support these features.

__awaiter(this, void 0, void 0, function* () { const result = yield someAsyncFunction(); return result; })

Spread and Rest

Offers a helper function to handle spread and rest operations with arrays, allowing for the combination and copying of arrays.

__spreadArrays([1, 2], [3, 4])

Decorators

Includes helper functions for applying decorators to classes and methods, which are a TypeScript feature for adding annotations and a meta-programming syntax for class declarations and members.

__decorate([decoratorsArray], target, key, desc)

Generators

Provides a helper function for working with generators and the yield keyword, enabling the use of generator functions in environments that do not support them natively.

__generator(this, function (_a) { switch (_a.label) { case 0: _a.trys.push([0, 2, , 3]); return [4 /*yield*/, someGeneratorFunction()]; case 1: _a.sent(); return [3 /*break*/, 3]; case 2: _a.sent(); return [3 /*break*/, 3]; case 3: return [2 /*return*/]; } });
