I hate clicking dislike on videos of creators trying to share tidbits with the learning public. But I hate more the padding, spending a minute telling me to guess what I don't know, many minutes setting up a scenario, then finally punching in something I yes most definitely did know and is not rare knowledge to most that have completed introductory reading on the topic. There has to be a better way. I promise if you just tell us what you're going to teach from the gate, we'll still watch

2 days ago I spent 6 hours trying to figure out why some code wasn't working, only to discover this little catch with the spread operator. I'm sure this video will save developers many hours!

Could you share the context? I am seeking some real examples for this problem. Happy hacking, bro!

which vs code theme do you use??

Another great video - I knew about this, but really enjoyed how you explained it.

Dude love all your vids I’m a full stack dev w/a passion for front-end, and I can tell you that you never stop learning. So watching your stuff is always a good refresher/new point of view on coding I love it keep turning out the content man! All the best 💯

Great job - really cleared me up.

Pointers in Javascript - good vid. For everyone whom might be unfamiliar with pointers: a reference is a pointer sans confusing jargon. Can't get over the fact that this video is so awesome; excellent discussion.

Learning something new every day great content 👍👍

I'd love to see deep copying be standardized in the language soon enough

This reminds me of dealing with pointers in C++ class when my professor at OIT wanted to make sure we understood pass by reference...he gave us four star pointers to work with as a project. Needless to say, pass by reference is no longer a problem. lol

Thank you for your analysis, very detailed。

Please can you share what is the settings that you use , its very cool that on the right next to the array when you mark it you can see the result

Really enjoyed that video bro

Thanks James

Hi James, I noticed that your vscode showed runtime value at the end of every line, could you please tell me how to do that?

Good tip that makes sense

JS is easy for 2 people. One who knows JS actually & other one who just know JS is easy. 😂

Nice video. Can you also do a video on Symbol and its uses in Javascript? Thanks...

Yey! I am in for the JS challenges 🦄

Got to know about this the tough way when i just started working as a web developer, i assumed spread op make a true copy and had to deal with a very frustrating debug session 😭

deep copy - shallow copy if we use the right terms

I just use the built in intellisense. If I'm working in a JavaScript file, it gives the recommendations.

Hmmm good info.

So I will be the 3rd who asks the same question. What vs theme do you use? So will you answer now?

I just understood a bug that I faced a few days ago

I am having a problem in HTML . Image is not showing/loading in Browser (Firefox) when html file is opened. I want image as background. My html file is in folder in D: drive and my image is in F: drive. I am using VS CODE (system setup).

Great video 🆒

Which vscode theme are you using I like it can you mention name

Yeah like it's kinda why it's called a spread operator, not a deep-copy operator. Funny, the thought this behavior could cause issue to someone never crossed my mind.

I love javascript

Uh, JS doesn't copy an array if you'd do: names = ['James', 'Jess', 'Lily', 'Sevi']; copyNames = names; ? It's just pointing to 'names'? Or did you just use that to explain how it works?

Torrent, I missed your intention. Yes b[]…a[] creates a pointer. Only basic types are copied in JS.

Same as with python.
