I will tack on my own opinion that building sites that only function with javascript is a massive disservice to everyone. From disabled people with accessibility needs, to old hardware/software, and even to security/privacy conscious people the JS paradigm is a massive problem. The trend for "new shiny" has become ridiculous and I find most modern websites to be pretty but rather useless. I have to scroll forever past slices with massive images and marketing lingo just to find something that seems potentially helpful but just goes on to more marketing bullshit.

Want to get my buy-in for your tools? Stop making them a hard requirement and make sure you have a non-JS fallback that works.
