hi dangling cruze,

here there no rocket science , doing here prevent event bubing. , stopping event reach @ web browser. preventdefault() method cancels event if cancel-able, meaning default action belongs event not occur. in single term

for example, can useful when:

clicking on "submit" button, prevent submitting form clicking on link, prevent link following url  @ document level binding main 3 event      keydown     keyup         keypress  , identifying key combination prevent key combination being used browser well.

let me know if require further help
