TypeScript - How can I access "this" in async method -

i have piece of code:

export class profile {      private resource: resource = new resource();       /**      * problem here      */     async initialize(): promise<void> {         console.log(this.resource);          var html = await this.resource.fetch(true);          const $profile = jquery(html);          console.log($profile.find("span.largetext"));       } } 

if can see line console.log(this.resource), undefined. can't async methods access "this"?

i tested console.log(this), , returns profile { } in web inspector.

is there way can access this?

class profile {      private resource: number = 1;       /**      * problem here      */     async initialize(): promise<void> {         console.log(this.resource);     } }   let p = new profile(); p.initialize();   let p = new profile(); p.initialize(); 

i created sample script transpiles to

var __awaiter = (this && this.__awaiter) || function (thisarg, _arguments, promise, generator) {     return new promise(function (resolve, reject) {         generator = generator.call(thisarg, _arguments);         function cast(value) { return value instanceof promise && value.constructor === promise ? value : new promise(function (resolve) { resolve(value); }); }         function onfulfill(value) { try { step("next", value); } catch (e) { reject(e); } }         function onreject(value) { try { step("throw", value); } catch (e) { reject(e); } }         function step(verb, value) {             var result = generator[verb](value);             result.done ? resolve(result.value) : cast(result.value).then(onfulfill, onreject);         }         step("next", void 0);     }); }; class profile {     constructor() {         this.resource = 1;     }     /**      * problem here      */     initialize() {         return __awaiter(this, void 0, promise, function* () {             console.log(this.resource);         });     } } let p = new profile(); p.initialize(); //# sourcemappingurl=main.js.map 

and output

as expected. conclusion it's not this keyword. it's resource class, guess.
