  • Mobile first - lyst.* is a responsive site and the mobile web experience is hugely important to us both in terms of functionality and performance
  • Progressive enhancement - not because we expect people to disable JS but because we believe this makes you build a better product. Speaking of…
  • Javascript - we favour VanillaJS over a compile-to-JS solution as with ES6 we feel we get all the language level features we need
