I'm complete newbie to react environment. Currently I learn basics from egghead begginers guide:
https://egghead.io/lessons/react-render-two-elements-side-by-side-with-react-fragments
https://codesandbox.io/embed/github/kentcdodds/beginners-guide-to-react/tree/codesandbox/02-react-create-element?fontsize=14&hidenavigation=1&theme=dark
In this course, Instructor programming everything in html file. But in codesandbox.io there is an option to create react sandbox with .js files
What's the difference in this approaches? Is this course deprecated in some parts? Is modern developing require .js files?
Of course, u can create a react app in one html file, but it`s much better to practice the right filing and separate the code into different files. F.e. HMTL code in HTML files, JS in JS and so on. U got my point.

I created a blog that uses markdown language for articles. I needed a beautiful and fast markdown editor for my website. I found website called
Readme.so which uses vs code to edit readme files. I did not find any information on how they did that.
I would be grateful if you tell me how to implement vs code on the website to edit md files.
Here is Monaco Editor for React. It's pretty straightforward to install with preference of your package manager and move forward with it like below.
yarn add react-monaco-editor

I was searching for a ready-to use web component for my Vaadin&Spring Boot application, and faced some questions.
As a person who does not into JS and frontend at all, i'm struggling in integration of those components. Currently I'm interested in this one: https://vaadin.com/directory/component/bluewatertrackspaper-countries/overview. I simply do not know what to do after adding a dependency via Maven. Could someone explain a way how to use those components similarly to default Vaadin components, using java classes?
Unfortunately the webcomponent you linked is built with polymer2. You can't use it in Vaadin 14+, except if you are running it in compatibility mode which I don't recommend.
It's easier to do it in Java with a Combobox.

I would like to verify that a string is valid HTML, like the W3C Service does. I specifically don't want any browser corrections (like closing open tags), which precludes options that create DOM elements and read the HTML from them. It will run very frequently, so I really need to run it locally. Libraries are OK, jQuery is OK.
Edit #1: I'm asking about HTML validation, not form or input validation.
Edit #2: What I need is basically a Javascript implementation of the Nu HTML Checker.
Provided you're running node.js or python on the server side you can use a library like html5-lint by Mozilla to do all the heavy lifting for you. And for the java world there is a similar library jtidy and there are countless of similar libraries out there.

I have an existing website, which is built on top of HTML/CSS/JS.
It has extensive theming, and over 10,000 lines of combined CSS (fancy animations and such).
I would like to move it over into my RoR app, however I cannot just drop it in a view because every import statement will break (that I know).
How can I move a site with many JS and CSS imports over to a RoR application? If I could drop it somewhere and let it just be as a static site that would be best. It just doesn't work because RoR won't accept the paths for my imports.
All help appreciated!
Thanks

I want to get the dates booked and price from the the airbnb page: https://www.airbnb.com.sg/rooms/2781352 under the "Calendar" tab of it.
I am quite newbie to this, and I want to python to do that, can I?
And what else should learn, javascript, PHP?
For extracting data from web pages, my first stop is Beautifulsoup. It is designed for just this purpose, and is excellent at it. Combine it with the great requests HTTP library (so much better and easier than urllib/urllib2/etc.) for getting the pages.
Both of these are Python modules, there is no need to learn any other programming languages to do it, although it greatly helps to have an understanding of HTML and DTDs (Document Type Definitions) for setting up paths.
