You should not put classes into Razor pages (as a general recommendation, there might be cases where it is desired). However, it is possible by using the @functions keyword. The following answer elaborates on that topic.

You can use ESLint's no-useless-escape rule, which will suppress warnings when you use escape characters that don't change the string's meaning. Also see this question and its answers.

As a bit of extra info, - in a regex only has special meaning if it's inside of square brackets [ ] and otherwise does not need to be escaped. None of the instances in your regex appear to be inside such brackets, so it's safe to say the regex will work the same if you do decide to just remove the escape characters.

I'm pretty sure the issue the texture your rendering to is 8bits. Switch it to a floating point texture (RGBA32F) You'll need to check for and enable EXT_color_buffer_float and OES_texture_float_linear

You say it won't work on mobile but you're using WebGL2 which hasn't shipped on iPhone yet (2021/1/3). As for RGBA32F not being renderable on mobile you could try RGBA16F. You'll have to check for and enable the corresponding extensions, EXT_color_buffer_half_float and OES_texture_half_float_linear. Your current code is not checking that the extensions actually exist (I'm assuming that was just to keep the code minimal)

The corruption is that your circle calculation draws alpha < 0 outside the circle but inside the quad. Before that was getting clipped to 0 because of the texture format but now with floating point textures it's not so it affects other circles.

Either discard if c <= 0 or clamp so it doesn't go below 0.

Note: you might find coloring faster and more flexible using a ramp texture. example, example2

Also note: It would have been nice if you'd created a more minimal repo. There's no need for the animation to show either issue

Something else to point out, maybe you already knew this, but, the circle calculation

As pointed out by @Kaiido, solution to your problem is here: HTML5 Canvas performance very poor using rect().

In short, just put your main loop code between beginPath and closePath without changing your theBoard.clear() method.

JQuery will try and load the scripts included in the HTML files that you're requesting. Is there a reason why you're including them that way?

Remove all the external script tags and css files from the html partials, or use a different method to include the html partials.

Also, those partials don't need to have or tags, best case scenario they get ignored, worse case, they affect the way that the browser reads the document and creates unexpected behavior.

It is because your function executed before DOM fully loaded.

Write function in $(document).ready()
