javascript - Get AsyncFunction constructor in Typescript -


so i'm trying dynamically create asyncfunctions in typescript program. mdn says can asyncfunction constructor 

var asyncfunction = object.getprototypeof(async function () { }).constructor;

but typescript compiles to

var asyncfunction = object.getprototypeof(function () {     return __awaiter(this, void 0, void 0, function* () { }); }).constructor;

the difference can seen attempting use constructor;

new asyncfunction("return 1;")();

returns promise (what need) when run in firefox, returns 1when run after being passed through typescript.

how can stop typescript mangling async functions?
