Javascript development as you see it today started budding with Mootools, Prototype, jQuery, YUI, etc. Wasn't until the early 2000s that the concept of unobtrusive javascript was even a thing. Then bundling assets came, asset pipeline concept from the rails world got popular in javascript land, then you had all the grunt, gulps, webpacks come into the picture -- Point being .NET came out in what, 01? So Javascript has a few more years, I think we will be in a good place in a couple of years. Besides that point, how much work behind the scenes before .NET was even ever released to us was going on? How many man hours of development was put before that first public release? My guess is a lot more than we think.
