How to make coderunner to run automatically when i save the javascript file

I have installed the Code runner extension to see the output inside vs code. I have an autosave option enabled. When I type code and click the “Run” icon on top , then vs code shows output below. But I want to see my Output just like “live server extension” in HTML /CSS where output is shown immediately without clicking anywhere. How do I do the same for code runner?
