Similarly, asymptotic complexity is not always an adequate approximation of energy consumption. More code leads to more cache misses. More code leads to more energy consumed transmitting that data over the internet, and wireless radios are energy-expensive. More code leads to more time parsing, compiling, optimizing, and then JITing code, which can utterly dominate actual runtime energy cost if the program is not long-lived - which describes a lot of webpages. Finally, very few webpages actually need to even be a "moderately complex React/Vue/Svelte app" - the essential complexity to the task being done is low, and webdevs add extra, unnecessary features for very poor reasons (showing off?). Take https://nabeelqu.co/understanding https://nabeelqu.co/understanding for example - 1.17M downloaded for 21K of text and two small images (one of which didn't load anyway). There's a 276K JavaScript file in there, among others - and the primary purpose of this page is to display a static document. Or, take any modern newspaper website you want - bloated with images, tracking, and JavaScript providing near-useless (and probably near-unused) features with a data-size:content-size ratio of over 100. If something is moderately complex, it would be much better as a native app in the majority of situations, which comes with significant performance improvements.
