Question

Frontend

for example, in AngularJS there are such concepts as controller, services, dependencies, module, scope and so on. and what concepts appear in these architectures and in React in particular?

Answer 1

in redux you have:
actions creators * - action creators. Functions that you can call instead of calling an action directly. For example:

function add() {
  return { тип: ДОБАВИТЬ_ОДИН }
}

reducer - reducer. A function that takes the current store object and returns a new one (with new data).
Total : in redux there are only three fundamental concepts: action (action), reducer (reducer) and state (store)
In react , there is even less: there is one concept - a component. And there, if you want: a smart / dumb component, a stateless component, and maybe something else.
ps in the function code there is Russian for clarity.
