      Why I prefer `const` over `let` and `var` The goal is to have less to think about.pic.twitter.com/2QBDga9U1R

      IMO using let everywhere gives you the least to think about ;) I do use const for actual constants though

      you're concerning yourself more about writing code than reading it. We read code 90% more than write it. Optimize for readers.

      fwiw I find "optimize for readers over writers" arguments to prove too much. Boilerplate has costs for readers too

      definitely a balance. Prudent to avoid dogma.

      confirm. My personal style is to use precious signal to point out unusual things, not common things.

      seems like a good approach. For me, reassignment is uncommon, so it's useful to call it out with let.

      but function parameters are `let` bound, which means (1) not uncommon, (2) no visual signifier

      I used `const-first` for a few months and hit this again and again as a source of mistakes.

          Another common cognitive confusion for me: const options = {}; // later http://options.name  = "kent";

          Rust doesn't have these issues and I appreciate const-first in Rust. Too many inconsistencies in JS for me.

          interesting. I have yet to have cognitive issues personally, but it's great to hear other perspectives.

          so you prefer let most places?

          I personally prefer a style with small methods as a mitigation against the kind of confusion const is solving.
