Why this pointing to global context is giving undefined, even when global variable is defined ? about javascript-algorithms HOT 2 OPEN

I guess, when you call "data.getStatus.call(this)", getStatus method setting the value of "this" to global object. But inside getStatus method, "this.status" trying to access global object property , not the status property inside setTimeout.

If we change getStatus function to arrow function, issue will get resolved.

getStatus(){ return this.status; }

@ManjulaP1012 actually the expected output should be "online" as this is pointing to global object status. but I'm not understanding why its returning undefined
