NodeJS http.request not returning data even after specifying return on the 'end' event

Question

Basically I am trying to scrap some data from website and perform the DOM extraction, deletion and updation on a callback function binded to the \'end\' event of http.

You cannot return a value from an asynchronous callback. Well, you can, but it most likely will get ignored and most certainly won't do what you want.

You cannot even return a promise in that place. You can only resolve a promise where you now use the return statements. You need to return a promise from the main function and then resolve or reject the promise in your event handlers where you use returns now.
