// One of my new favorite React Hook patternms is to create handler
// functions for a custom hook using `React.useMemo` instead of
// `React.useCallback`, like so:

function useBool(initialState = false) {
  const [state, setState] = React.useState(initialState)
  
  // Instead of individual React.useCallbacks gathered into an object
  // Let's memoize the whole object. Then, we can destructure the
  // methods we need in our consuming component.

Привет!

Ключевые слова: coroutine, continuation, generators, async/await, project loom, free monad, algebraic effects.

Я хочу сделать алгебраические эффекты для Clojure(Script). Я уже сделал библиотеку https://github.com/darkleaf/effect/blob/doc-2/README.md Но есть моменты, которые вызывают у меня вопросы.

Если очень кратко, то лично мне эффекты нужны, чтобы:

1. удобно тестировать бизнес логику

ClojureScript REPL Workflow

Short write up on using REPL when developing UIs in ClojureScript.

Hot-reload on save or Eval in REPL?

Everyone's standard approach to hot-reloading is to use a tool (Figwheel or shadow-cljs) that reloads changed namespaces automatically. This works really well: you change the code, the tool picks up changed files, compiles namespaces and dependants, notifies REPL client which then pulls in compiled changes, and re-runs a function that re-renders UI.

The other approach is to use ClojureScript's REPL directly and rely only on eval from the editor. This more or less matches Clojure style workflow. This approach might be useful when you don't want tools overhead or hot-reloading becomes slow for you or you just used to this style of interactions. Also changing code doesn't always mean that you want to reload all the changes. On the other hand it is very easy to change a couple of top-level forms and forget to eval one of them.
