I've been working on and off for many years on https://ssa.tools/ - a site that helps folks figure out their social security benefits for retirement planning. I recently added and continue to iterate on a new feature for specifically helping you understand the tradeoffs of choosing different filing dates at https://ssa.tools/strategy - it was interesting trying to optimize the performance enough to let the user drag sliders and get 'instant' response time, especially in typescript.

Does it have to hit an API when the user drags the slider? In any case, I can't imagine why TypeScript is the bottleneck.

Ah, the entire site is static. That way nobody's personal financial data ever hits my server.

I’m trying to understand what’s going on when they touch the slider. If it’s all local, what’s the process creating output? What kind of “optimization” did that need to be more responsive?
