One thing I love about these videos is just watching your workflow and seeing how you use and read documentation. It's like there's a mentor by my side showing me how to navigate this confusing world of self taught programming. Thanks

[@tonym_123]

incredible, how do you make this look so easy? like seriously, i would spend hours just to make half of what you did here. you are truly an inspiration

[@RicoMinovo]

If you watch it at 1.5x he is even more excited to teach programming. Thanks!

[@Matt-tn2on]

Man I have no words. Daniel Shiffman, you are simply the best!

[@fastlearner9993]

your TEACHING style is one of a kind !!!!!

[@prernasharma3439]

Loving this series so much. Thank you so much for making JS fun.

[@ShujathHussain0]

After so many series and lectures. i just love the energy & clarity of your every explanation

[@MrUgleh]

Although I have no need to watch this series because this kind of stuff is my bread and butter, I still do because I love watching your videos, and you never know what you will learn. There is always room for improvement. With that said, I think an addition to this "Working with Data" series you could show how to cache data that doesn't need to be repeatedly fetched from the source. Just an idea but picking up from this video, you could grab all the countries latlong via restcountries.eu, which also uses no authentication, and then create a marker that displays their population or something, or using Charts.js create a bubble map that involves area, population, exc.

[@TheCodingTrain]

Ah, thank you for this feedback! A great tip! Feel free to keep commenting with more feedback as I release future videos.

[@julietosunde9475]

You are awesome!! this has helped with a project I have been struggling with for days now. Thanks

[@vishalchauhan9832]

@Juliet Osunde on which project you are working.

[@naveennani1772]

It helps me too . 🙂 But we can't share anything about our project as it's against our company policies 🥴

[@RicoGalassi]

Love this series. Been teaching me so much! Very excited for the last one! And definitely please show how to center the space station while the map moves around it so the ISS is stationary. Can you definitely also show how the page can update with the new lat and lon without refreshing? Love your videos!!

[@TheCodingTrain]

It's all coming in the subsequent videos and you can find the exercise solutions here: github.com/CodingTrain/Intro-to-Data-APIs-JS/

[@SimonTiger]

0:14-0:16 In case anyone hasn't noticed, that was Dan from waaay in the future. That's why his voice was a little bit different. Because, I've actually watched how he recorded this, and he just said "dom" incorrectly. For some reason, that bothered him!

[@TheCodingTrain]

Wow, amazing that you noticed!

[@MiladAKareem]

Very useful video. Thanks for all you share with us.

[@pastorhudson]

Dude! I love your teaching style. You’re killing it! I love the setup too. Green screen? How do you know where to point? Do you have a monitor like the weather man? It looks fantastic. I teach for a living and this is one of the best coding style lessons I’ve seen.

[@TheCodingTrain]

Yes green screen and monitor! More here: kzbin.info/www/bejne/qaLOqHuLrrtgj7s

[@enivaldobonelli]

Beautifull lecture. Thanks a lot, Daniel!

[@RugShadow]

Hey! Your videos are absolutely great, and coding along with them each in order has taught me so much! There's one thing in this video that has me absolutely stumped right now and I'm surprised I don't see anyone else mentioning it in the comments- when I paste in the attribution URL, the URL itself has quotes in it, which JS then treats as the end of the string! How and why is it not doing that for you?

[@thaiscorreia9072]

You're a life savior!

[@Any_key404]

Dan, VSCode has Emmet built in so you can all kinds of HTML stuff really quickly, like making divs or setting up a boilerplate page. Is this something you normally don’t use or is it jus out of scope and confusing for people browsing your videos to see you do something like .name and a line of code magically appears?

[@TheCodingTrain]

Oh, I should look into this more, thank you!!

[@mariusbrinzaru8137]

A great tutorial sir it was a pleasure to watch!

[@kasta867]

Amazing tutorial, just what I was looking for!

[@Dadaadad268]

Where did the tileUrl come from? I know you explained it a bit, but can that url be found in documentation anywhere?

[@jeansylvestre9270]

You're a genius !

[@t_apk4477]

Great Tutorial. Please suggest to restrict the tile to only 1 rather than many more when u r zoom out, please reply

[@prashanthkumar5987]

Awesome dan🤩

[@lipslide101]

Hey man nice video! I would like to suggest you using npm instead of good old vanilla import into html because that's rarely used in the real world for real applications. Everyone uses things like npm and webpack which is a really essential tool. I think it would be a good idea to always use that even if it's just for good practice and not really necesary :)

[@darkceptor44]

I personally don't mind, I'm too lazy to create even more projects on my hard-drive so I prefer using online services like codepen.io and repl.it to host simple CSS/JS code, and I already had to change my code a little bit because there's no async and await on browser JS so using NPM and other Node libraries would make it harder for me to keep using it on browser. Btw when I do use Node/NPM I prefer Gulp not Webpack, it's JavaScript style and not JSON style, 100% recommend it.

[@TheCodingTrain]

Ah, good point, I should add to this series to cover this.

[@IceMetalPunk]

NPM is good for Node projects, but when making a fully client-based application, there's not much need for it. To be honest, the reason things like Webpack/Babel/etc. seem to still be used for client-side applications is just for compatibility reasons, but if your application doesn't need to support old browsers (*cough* IE *cough*) then most modern browsers will be just fine with vanilla ES6 features.

[@EricWilliamsCG]

Have to agree with DarkCeptor and IceMetalPunk. I use vanilla often in real world apps. NPM is just another link in the chain to keep working.

[@lipslide101]

I just find that me and my colleagues always have been using npm for the frontend of our projects, just to keep things clean. But yeah it was just a suggestion :)

[@johnhodgkiss9882]

Great video. How would you click on the target to open another window or perform a function related to that marker?

[@vahidsediqi5638]

I would love to learn Nodejs or Reactjs from you!

[@MrMaraxli]

i really like how you teaching and explaining. i just start learning javascript and i wanna know do you have javasript tutorial videos like about everything. thank you so much

[@AndreaVitiani]

great video as always!!

[@gloubiboulgazeblob]

Nice. Maybe giving it a try with Openlayers ? Doesn't it offers you more possibilities ?

[@shmihshmih4287]

Great video! Thanks!

[@rafiel767]

Love the videos! I am wondering though... Some data seems to be changing but you still used const, instead of let. Why is that and how is the code still able to work?

[@nigusukassahun]

The marker doesn't pin to the map accurately when you insert your own icon, like it normally does when using its default icon.

[@hongvicodes]

Hey nice video and great presentation, period. But how can you preview your work on VSC ? I was wondering about this for weeks. Thanks in advance.

[@furiousjanush5776]

Great job!

[@andresmontoya7852]

Thanks! Might you make a project with the following option: If I type "Colombia, Bogota" on a input, the library you used can change that text to lat and long? That would be awesome!

[@EricWilliamsCG]

I recently set up a site that works with Leaflet and Algolia Places that does that. Algolia Places gives you real time update as you type addresses with latitude longitude, leaflet can then update the maps with new data how ever fast you allow it to.

[@andresmontoya7852]

how did you figure out the appropriate values for iconAnchor?

[@prithwirajdutta3827]

Daniel could you make a video on how to optimize route on a map like the Mapping companies do ! Also, it would be great if you could make an application that uses drag and drop workflows like Salesforce does inorder to automate its applications.

[@prithwirajdutta3827]

Thank You.

[@marchino3577]

using leaflet how do I get the set of coordinates of a place sought through the search box and highlight its borders

[@Pierstoval]

At 7:35 you say that {x} and {y} are for latitude and longitude, but that's actually false. There's a special equation/calculation system that determines the tiles numbers, based on width+height of the global map + the current zoom level, so x and y will not actually reveal latitude nor longitude :)

[@TheCodingTrain]

Oh, this is a great point, thank you for this feedback! I need to keep a list of corrections somewhere.

Hey great video. Is it possible that when I click on the map, the coordinates are displayed or copied from there?

[@Choedron]

I am trying to use this to show current location of a SPOT tracker. Problem is, the JSON file contains several latitudes and longitudes - this does not work. It is also possible to retrieve the latest position - but as an XML. I have tried this, with the above script. But that does not work either. Is there any way to retrieve the data from an XML file instead? (Mind you I am not that experienced with geolocation).

hey there good people, just an add on this, if you are using vue3 the icon/ marker might not appear hence , according to the documentation at this point in time, you will have to add : import { Icon } from 'leaflet'; delete Icon.Default.prototype._getIconUrl; Icon.Default.mergeOptions({ iconRetinaUrl: require('leaflet/dist/images/marker-icon-2x.png'), iconUrl: require('leaflet/dist/images/marker-icon.png'), shadowUrl: require('leaflet/dist/images/marker-shadow.png'), }); to your main.js file and voila your marker appears! happy "mapping"
