javascript - Investigation of specific lines of code on github -

hey guys debugging jquery carasoul plugin , came across following lines of code ::

 $next.addclass(type)  $next[0].offsetwidth // force reflow 

ofcourse , mean little , can have @ source on git here.(check line 147).

now , question s not lines of code doing , question :

sometimes when going through github repository , come across few lines of code make little sense , if these lines of code debugged , still persists make little sense , lines of code above example of trying say.

now in such scenario, person left 1 option , check comments on git repo specific line of code , question "how go doing that" ?? . tried "blame" button , litterally gives me no info why lines of code added . place on git go , find out "why these lines of code added ??" .

thank you.

tenali.

using blame button info you're going - shows comment left revision on left along author. unless code commented, other way asking author themselves.
