all(...action) ⇒ object

Combines several actions

Returns: object - combined action object
Params

• ...action object - action to combine

Description

import { ACTIONS, reducer } from 'general-reducer';

const state = {
    a: {
        a1: [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]
    }
};

const trim = (path, n) => ACTIONS.all(
    ACTIONS.shift(path, n),
    ACTIONS.pop(path, n)
);

const updated = reducer(state, trim('a.a1', 2));

// or

const updated = reducer(state, trim([ 'a', 'a1' ], 2));

As a result we will receive new object with structure below:

{
    a: {
        a1: [ 3, 4, 5, 6, 7, 8 ]
    }
}
