this is really excellent I am part of a meet-up of theorists who do build websites... but are also curious how frameworks like React work under the hood. What algorithms they use, frameworks, etc. It's possible to build a nice web-site without knowing any code at all. Or knowing some code and algorirthms. In that case the code may become very difficult to control, or revise or share with your peers. If you know some algorithms and code it's sometimes helpful to see what is under the hood.
