[@pguti778]

Yes!! Also add how is the correct way of doing!!!

[@rohitjha7202]

on fifth, instead of checking else if(arr.length===0) you can check else if(arr.length) only. very good video. thanks

[@JamesQQuick]

Would you still need the “!”? So (!arr.length)?

[@rohitjha7202]

@@JamesQQuick yeah, just one if condition needed (!arr.length).

Hey James, just subscribed. What plugin are you using that displays the log on the right, that is pretty cool as it is able to evaluate the if condition

[@JamesQQuick]

Hey hey! It’s the quokka extension. I’ve actually got a video about it :)

[@mt7270]

what editor you use?

[@pguti778]

Great video!!

[@vishalvmulgir]

Great tutorial thanks ❤️

[@JamesQQuick]

Glad you enjoyed it!

[@konser802]

Hey, James! What is the editor do you use in video? I really like it!

[@aka5]

It looks like vscode with some cool plugins (seems it's the quokka extension)

[@WilCODE_]

Any one know the name of the extensión that show you console.log without go to the browser or terminal?

[@JamesQQuick]

Quokka extension. I’ve got a video on that one as well :)

[@MediumSizeNoob]

Hi Sir, I noticed that the is a square marker on the left side of the code. Where is that coming from? Thanks 😁

[@JamesQQuick]

I’m not sure. Do you have a time stamp I can look at?

[@MediumSizeNoob]

In 2:56 just beside the line numbers 😁

[@owainharris]

@@MediumSizeNoob That is from the Quokka extension. It's basically saying green means that line is valid code, if it was red it would be an error (I think) - not sure what the white means.

[@MediumSizeNoob]

@@owainharris Oh okay got it thank you 🙃

[@darkseid3427]

Man can you please make a video on vscode for complete beginners for web developement

[@lucasmendonca2197]

Why is the empty String considered falsy but not the empty array and empty object ?

[@JamesQQuick]

I think it’s the difference between primitive values and objects in JavaScript. Since strings are primitive values, empty becomes false. But an empty object of array is still a valid object.

[@29namankumar29]

Hi James! I'll vote you as the top #ProWebDeveloperOnline !👍💪

[@JamesQQuick]

Haha thank you!!

[@sokoyaadedolapo5321]

What I do when it comes to array is check for the length.

[@JamesQQuick]

If it’s undefined though you’ll get an error if you try the length :)

[@tipeon]

The real question is: who made the mistake? The developer or the designer of the language?
