Very clear. Thanks. Had read about these 2 things multiple times over the years but could never really wrap my head around them. Now I can.

Thanks, I understand this finally, after almost 2 years doing software development. You should have written Mozilla documentation.

[lbrevilation]

why do you put a link if you dont want any action on it ??, why we use exactly PREVENT DEFAULT()?, can explain me ??

But... how to deal in case if i have onclick action on parent (red box) element and i need to access exactly parents event.target, but user click on link area (he can do it). Think of some fancy tab, button or some card with icons, texts etc. event.target will return the element user was clicked and it not always will be parent (where onclick actually was attached).

now what is stopImmidiatelPropagation() ?

[jjsmithlago]

Does anybody else ever get "TypeError: Cannot read property 'preventDefault' of undefined". i've NEVER gotten preventDefault to work. It always does this reaguardless of what I'm doing with it.

When I heard you talking I immediately wanted to give you a downvote. But the content is actually good. Understandable and not too long also. Well done. You just happen to have the speaking habitus of someone living on the street ;-)
