To put a finer point on his argument; I'm working on an Angular project at the moment. Every time I refresh the page I have to wait 10 seconds before I see any of my changes while Angular compiles everything. I calculated that, given the number of times I have to refresh to test my changes, all of those 10 second compilations is costing my client tens of thousands of dollars every year in wasted productivity. So I can't help but wonder how Angular and their ilk are better?
