Any video from you is great. You present every function in detail and practically. If a person doesn't understand it after your video, he probably never will... Thanks
Hello, I am using a translator, well I speak Spanish not English, but I want to tell you that your videos taught me a lot, they are incredible and I have learned a lot
I would say - You Rock the House Man.. You just finished within 12 minutes unbelievable with real time problem statement.. 100% useful video. Thank you so much from INDIA.. This video should be watch millions millions times...
bro please make a javascript full course like the html css course, it was the best course i have ever bought and i would 100% buy a javascript course from you
Excellent tutorial!!! I must say by far the most high quality, precise one in web dev I have seen in a month. Please more JS/DOM related tutorials. Btw, which VSCode theme do you use? Looks pleasing on the eyes. Thanks in advance. Keep dev'ing!
Thanks for the kind words 💙 There will be more javascript videos (and dom) in the future. My VS Code theme is Palenight but in the video I am actually using a different app for coding. It's called RunJS, which is a simple javascript playground with integrated console. If I just want to try out a few code examples I use that app so that I don't have to setup an html file, open the browser console etc. For development I would not use it as it has very limited features but when I simply want to mess around with a little bit of js code, it is faster and simpler to use RunJS.
@@coding2go Thanks for your explanation. The theme looked well colored to me. I used Palenight for a while, but somehow switched to the GitHub Dark Theme.
This is the one-line arrow function that I explained at 2:44. You could write both examples in one line, but I decided to use an extra line because the &&- condition was too long.
You use curly braces when you have multiple statements in your return and you use brackets when you have more than one argument or parameter. If you have only one then you don't have to use them, but your code will work if you use them
Hi, you remind me of me - don't stress, it will get better with time. Remember that parameters are sometimes referred to as arguments. For every parameter remember that - it is [ data - (information you have to give) ] that you have to pass(give) in your function for that parameter or argument. Remember that in javascript [ arr ] is short or shortcut for array and [ i ] is short for index(you will find [ i ] or [ index ] are part of all arrays. Always remember when working with arrays that an array stores data that is supposed to be a list of things(data). For an example: when you are working with an array of numbers // const numbers = [ 2, 6, 7, 10, 43 ], you will be using [ num or n for number not numbers ] - to pass data to that [ index(specific) parameter or argument of (num or n) ], hence price not prices because you are referring to a specific index or [ i ] of that array - a specific element of an array... // const prices = [ 3, 6, 7, 9, 23, 78 ] // prices.map(price => price * 0.5). Explanation of prices.map - go through prices array. Explanation of price inside brackets - use a single price of an array. Explanation of price * 0.5 after =>(arrow) - use that price( index or [ i ] ) and multiply it by 0.5. I hope it helps.. but believe me, it will get better with time.

Yes you will. Our "members-only" videos are the individual lessons from our html css udemy course uploaded on RUclips. By joining you unlock every video on this channel.
I never really used filter I think it might be a little better then map and can server the same purpose. I hate reduce I always get that confused. Map is better but filter according to this video
Just so you know, the best way to use filter and reduce and forEach etc. is to not. Don't use them. Use a loop. Loops will seriously uncomplicate your code. Half of these methods need a callback that looks the same but does different things, and all of them are slower than a loop (and I hate slow websites).

Thank you so much 🤗
the best... video on map, filter, reduce
pls make one on async -> callbacks, promise,...

You are good.. you are so very good. Thanks for the video - concise and easy to understand
Thanks man ❤
may i have questions?🙇🏻♂️🙇🏻♂️

He used short arrow function
This is the one-line arrow function that I explained at 2:44.

@@coding2go thank you very much

Thank you so much! respect!
Pls make a playlist on DOM manipulation 🙏
Great video ❤ please install more js😅
0:30 This reference is not LOST on me.
👀
Great tutorial
Thanks you so much for this precious video
Great🎉
Superb, fantastic 👏 👌 nice explanation. Post videos on es6 features indetail 🎉
Hola hola... Are you using an extension to see the log outputs?
Is there any explanation, regarding those 3 parameter?
Like what's arr, i, price means?
Im still new
You could watch my video on the foreach method to find out what these parameters do. They work the same in all of these methods. Hope that helps ✌️
@@coding2go thanks

Can you do a tutorial on function and Dom please 😊😊😊
can you create a tutorial on how to properly use the css units such as, rem, em, % and px, pls
can u make a tutorial on JS
This is a tutorial on js. How about can u make more on ts lol
Laptop is cheaper than smartphone 😂
Well, it depends?
ithink if you do know how to build pc, pc will be cheaper than those 2 but with higher specs, but the cons is you cant bring it anywhere 😢
What software is being used here?
I am using RunJS, which is just a simple javascript playground with integrated console. If I just want to try out a few code examples I use that app so that I don't have to setup an html file, open the browser console etc.
when next video about find method and etc?

Don't use them.
Use a loop.
Loops will seriously uncomplicate your code. Half of these methods need a callback that looks the same but does different things, and all of them are slower than a loop (and I hate slow websites).
Awesome . I'm super grateful that I know this now !
Glad I could help!
Need dsa in python.
