tell me about it! Or, heaven forbid, just make the user get the entire html page rendered from server after every click like it's 2003 or 2004!
A lot of (admittedly badly coded) "modern" web apps ignore basic web idioms (like hyperlinks) and assume as unique single user workflow the one its designer tought the app (and the only one he tested).
Just to give an idea how bad it is: loading the front page cold of new reddit = 9685KB. Loading the front page on the old reddit (also cold) = 737KB. The compute profile is literally half for old.reddit.com (new peak 16%, old peak 7.5% - both metrics core-distributed over an 8c system; 1s sample rate).
I LOVE all of this talk that front-end devs like to have on optimization/state stability. Talk to an browser automation expert, esp. one that does it at scale. Almost 100% of the time older/simpler front-end tooling/development is faster and less error prone. Older also takes a FRACTION of the compute/memory/proxy resources. It's been this way for years!!!
ducks for the inevitable storm of HN hate for having a strong opinion
