This is absolutely brilliant. Attaching a storyline to this was genius. This is how everyone learns; through context and use cases. Keep to this style of tutorials and this channel will sky rocket. Well done 💯

Thanks Lothar!

History in tech is important. Someone needs to do a video of the history of the internet (from a network point of view)

[@Speglritz]

We transpile typescript to javascript then transpile javascript to older versions of javasript for wider browser support and then the browers JIT compile the javascript it loads to run the actual code. Even without webpack, different loaders, webassembly and the other stuff going on it's complex enough.

[@marianrys316]

Great stuff! Thank you ! In less than 30 min you fast-forwarded me from the 90's to modern era :)

[@LachlanMiller]

Thanks ⚡️

[@brentleemans]

Amazing video! With every part you explained WHY something was needed. This is missing in most of explanation videos on the internet. Thank you!

[@paperC_CSGO]

The video I have been looking for as a junior developer - to actually try and understand the bigger picture and fundementals. Please make more of these type of videos! You are hitting a much neglected part of the web development KZbin tutorial/course/explainer videos market!

[@LachlanMiller]

Thank you! I'l do my best, glad it helped you, good luck!!

[@johnphillips8600]

This is the best explanation I've come across... Most videos are too long and too minified. Thank you for this ❤️

[@LachlanMiller]

Glad you found it useful!

[@pkproductions1623]

This video is awesome. In just 25 minutes you explained the whole modern javascript paradox. How a simple button click in JavaScript is evolved to be so complex. Thanks a lot it made me understand concepts that are very confusing.

[@narayan1509]

One of the best video I come across while searching for basics

[@Usmankhaled]

Absolutely brilliant. Seems like you witnessed everything as if you yourself was a kernel routing and directing every piece to work together just like that :)

I'm honestly impressed with how good this was to give and idea about how we ended up using all of these tools in the modern web development. Thanks for your effort!

[@uchihai_a_h4871]

now finally all the dots got connected... brilliant mate !

[@user-zw7go3we9f]

This video is really helpful to me. When I dive into Huge numbers of libraries from single page with HTML CSS JS. it really drive me crazy. But thank your sharing. I understand a lot and get a clearness feel.

[@XpressBits]

Best tutorial watched in the recent days.. Precise and no BS... you got a great teaching skills, mate! Please keep doing the videos..

[@LachlanMiller]

thanks!!

[@johnas3]

Bro you are now my new history teacher. Great work and thanks for the explanation🔥

[@user-tt6nc6mo7k]

This really confused me too when I started learning web development. Now I have a great resource to refer to other people thanks! On another note, I see you have a few videos on testing using Jest, Cypress, etc. I personally am quite new to testing I understand there are different types of tests like unit testing, integration testing and end to end tests. I know what each of them are but I do not understand how they all come together in one project? Would be great if you could do a similar overview type video on how all these are implemented in a production application.

[@LachlanMiller]

Yeah this stuff is confusing - there is way more tools in the average project too, but this is the general idea. Sure, I will definitely do more content around all the different types of testing... great suggestion. One of my favorite topics.

[@jhonyortiz5]

This entertaining and very eye opening when it comes to the past couple decades of web development. I hate when people use simple examples that have been simplified so much that they don't represent reality anymore. But your example was as simple as it needed to be but no more. It's really cool to see how it all really works and how it came together.

[@fogguy3838]

exactly what I was looking for, Thanks, great job

Main focus is around Vue, but definitely could look into some more generic tutorials on concepts that apply to both React and Vue.

[@bhavyabansal1143]

@@LachlanMiller if you ask me, I will say that given there are lot of tools out there like your video has explained, it will be good if you can make individual in depth videos of each tool and explain different configurations and what they are used for. I am happy to help as I am also learning these things and there is lot to learn out there.

Thank you!

[@kashnigahbaruda]

As a newbie this was great. Struggled today with some jest testing presets and had absolutely no idea what was going on. I think I solved it because the error went away but I am worried the test was just skipped. Luckily I have no idea how to check which tests was skipped or not so I can go to bed without worry.

[@LachlanMiller]

Glad you got it working - skipping a test is never ideal, might be good to find out why it's failing lol. Sleep tight

in babel.config, how wepback knows the order to use ? in case of tsx, which loader is gonna run first ?

It goes in the order of the array. I think it goes last to first (weirdly enough).

[@codybontecou]

If given the choice, would you support ES5? It seems a lot of this complexity comes from supporting old browsers.

[@LachlanMiller]

Depends, last job I worked we had a lot of users on IE11 (hospitals) so we just used babel to target es5. Nowdays browsers can actually load es modules natively via , so depending on your project you might not even need webpack, just a simple typescript build that exports modules, but I think a pre-configured setup (vue cli, create react app) is probbly the way to go.

[@georgewinchester6403]

Why do we bother with ES5 when approximately 95% of web browsers understand ES6?

[@LachlanMiller]

Because 5% don't :P I don't bother with ES5 unless I know I need to support older browsers. Here are some use cases I've run into for ES5: - healthcare (often need to support IE11) - smart TV UIs (often using old versions of Chromium or WebKit)
