- The one thing that always confused me when I was learning JavaScript was what exactly the "e" or "ev" was when using events on things like button clicks or mouseovers - in this video, we take a look at how this object is useful for JavaScript coding.

As a few people have pointed out, the parameter "e" can be named anything. Other common names for the event object parameter is "ev", "evt" or "event".
Here it is. If you call it not an event ("e" or "event"), but an object, then everything immediately becomes clearer. This is an event OBJECT! And this object has properties: .target, .ctrlKey, etc.
Thanks for the video.
Out of all the videos. I found this to be easiest and straight to the point. Thank you sir.
Great video and advice! I was a little hazy on my full understanding of the Event object , now I full understand it!
Great video man! Made this a lot clearer for me. Subscribed!
Wow, very well explained. This helped a lot. Thank you!
That's great! This is exactly what I needed to understand event.target. Thank you!
Thank you, this video made it easier to grasp the concept behind the event object
This makes things so much clearer

I am searching for this finally I found it. Thank u so much.
Thank you bro, I was stuck with this, now you explained.
Crystal clear explanation. CRYSTAL!
I was about to write the same exact words: crystal clear! You're very right. I know sometimes people or teacher's methods are fine for some persons, but I didn't really get it since this video.
@@LaGrossePaulik I also understood only after watching this video

@@dcode-software fortunately emojis are universal.
thank you
Man you're awesome
You too
Thanks
Came here to tell you that you added an extra round bracket to the function in the thumbnail 😂😂😂. Nice tutorial btw.
🤣🤣 oh no.. probably going to leave it
At the opening of the video you can see where it came from. It’s a cropped image of the adding of an event listener. The opening parentheses just got cropped out
@@gmangsxr750 nice observation
Brilliant
Cool theme, can I know the name of the theme please?
I get a pointerEvent instead of mouseEvent is that wrong?
i love you
What is the name of theme?
(e) contain informations about event
which font?
Roboto Mono
Would have been nice to explain too why "e". Can it be any other variable name, I assume that 'e' is used for simplicity, shorthand and laziness. but it could be "event", or "eventProperties" or "banana" - as the developer sees fit.

your a fuckin g bro

So to break it down for a stupid like me. Everything that is an event and is performed gets stored in a bundle of informations. In this case the e object.
is this deprecated?
*e*
E
First
Hmm...
Why don't everyone just explain things like this? Teachers make things so complicated for someone who is new to programming
Which clown thumbs downed the video
Always that one guy, haha.
Kinda confusing video, the conditional statement if(e.ctrlKey) doesn't actually check if the ctrl key is being pressed down or not, just if that property exists at all with the event object, regardless of it's Boolean value.
What an incredibly bad video. What you're explaining in this video is what's inside the parameter passed to the callback function you provide to an event listener. But in your title you say that this is always the case when you see (e) in some code. Even in this case it 'e' can be named no matter what, some people like to name it 'event' etc...
Worst video ever. Logged e to the console and checked mdn docs. Damn, never would have thought of that.
thank you!
