How do I read the following arrow function

Question

How can I read the following arrow function in English? I can understand that there are 2 parameters namely dispatch and getState. How do I read the remaining part?

How to write it as a normal function?

    const apiMiddleware = ({ dispatch, getState}) => next => action => {  

Answer 1

Written as a normal function, the declaration will look like this:

const apiMiddleware = function({ dispatch, getState}){
 return function(next) {
    return function(action) {
      return something;
  }
 }
}
