As you might know, most common video container files are like zip archives that contain several other files: the actual video, several audio files for different languages and several text files for subtitles and captions. If these tracks are included in the video file, that's called packaged afaik.

Now, while HTML offers the element to reference additional files, are browsers capable of choosing among different packaged tracks and display different subtitles?

How is browser support?

I have an application using ASP.NET Core MVC and an Angular UI framework.

I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:

Uncaught SyntaxError: Unexpected token '<'

These pages look like they are loading the index page as opposed to the .js or .css files.

Here is a snippet of the underlying runtime.js as it should be loaded into browser, it is not loaded with index.html.

I'm getting following error on some devices while opening url. I don't get any error on my devices but many devices are.

In this app, When i submit a word (for eg help) for the first time then it will return the search results and renders it on the page, but if i searched for another word then the results wont be displayed until and unless i refresh the page. How can i render next search results on the page? The codepen link is here: https://codepen.io/nelsonuprety1/pen/KKWreRQ . To search for new results the page should be refreshed.

I am trying to perform a Fetch request to an external API, and it should return some JSON data. I have tested the request in my browsers console and it worked fine, however as soon as I add this code to run when I submit a form, it doesn't seem to do anything. No error, it just does nothing.

This is my function:

MDN says:

The yield keyword causes the call to the generator's next() method to return an IteratorResult object with two properties: value and done. The value property is the result of evaluating the yield expression, and done is false, indicating that the generator function has not fully completed.

I ran a test in Chrome 91.0.4472.77 and it appears to be a fresh object every single time. Which seems very wasteful if the processing is fine grained (high numbers of iterations, each with low computation). To avoid unpredictable throughput and GC jank, this is undesirable.

To avoid this, I can define an iterator function, where I can control (ensure) the reuse of the {value, done} object by each next() causing the property values to be modified in place, ie. there's no memory allocation for a new {value, done} object.

Am I missing something, or do generators have this inherent garbage producing nature? Which browsers are smart enough to not allocate a new {value, done} object if all I do is const {value, done} = generatorObject.next(); ie. I can't possibly gain a handle on the object, ie. no reason for the engine to allocate a fresh object?

While using NodeJS, the URL was localhost:3000 and while using flask, it was localhost:5000. Why are they different if both running on same browsers. What is the key difference? Are there any others in different web technologies? Can we run NodeJS on 5000 and flask on 3000?

Not sure if I'm doing something wrong here or whether this indeed is a Chrome rendering bug.

Here is my very small example:
