Nah, nah, it was the International Phonetic Alphabet. Can’t have something like that on the 'murican internet.

Do you understand the functioning of both interpreters, down to the CPU instructions? How the database you’re using performs those updates, or quickly finds your items? The precise function of the virtual DOM? TLS handshake protocol? If so, good on you, but you don’t need to know more than the surface level of any of these for a CRUD app. But these and other systems you use hold the raw power, and wielding them poorly could lead to bugs, or security or performance issues.

On the other side, whatever you do may seem mundane to you, but lighting a fire would seem mundane to a sorcerer the umpteenth time they’ve done so. A simple CRUD app could seem dramatic if you have no idea where you’d even start building one, which is the state the majority of people are in.

None of that is chromium. Vivaldi could have built that on top of Firefox, but didn’t. As to why Firefox is better, the very fact that it’s an alternative that is keeping up technically is a benefit. It’s less a ‘V-shaped engine’ monopoly and moreso a ‘V8 engine made by a specific company’ monopoly. They have far too much control over the direction of web standards. Much of what they are doing is actually good, but it should then be spread based on merit, rather than because they directly control almost the entire market.
