JS has gotten slightly faster, but not much. JS isn't really a bottleneck anyway.
Six years has also increased the pixel count by 10x (150k pixels in the iPhone 1 vs. 2 million in the SGS4). The hardware has barely gotten faster relative to pixel count, and in some respects (such as memory bandwidth) has gotten slower.
The web is no more viable on mobile today than it was 6 years ago. Web doesn't do efficient - never has, probably never will.
