Wtf plunker. I decided finally when asking questions it would be convenient for devs to answer when they have example in plunker or some other platform where can code be edited and exectured. And I cannot do simple thing - create a file. Wtf. Now I am googling for tutorial how to create a file in plunker. Wtf idiots. File creation should as easy as clicking right mouse button and creating fucking file. And now it opens browser contect menu wtf !
