About the test

The React Redux online test uses live coding tasks to assess the skills required to build front-end applications with React and manage the application’s state with the Redux Toolkit.

The assessment involves solving work sample tasks such as:

  • Creating reusable Components.
  • Handling user events and updating the application based on user actions.
  • Creating a store, reducers, and dispatching actions in Redux Toolkit.

A good React developer using the Redux Toolkit needs a solid understanding of both libraries to build and maintain complex front-end applications.

Managing State

The Message component contains an anchor element and a paragraph below the anchor. Rendering of the paragraph should be toggled by clicking on the anchor element using the following logic:

  • At the start, the paragraph should not be rendered.
  • After a click, the paragraph should be rendered.
  • After another click, the paragraph should not be rendered.

Finish the Message component by implementing this logic.

 Consider the following Redux reducer defined to manage a wish list:

const wishListReducer = createReducer(initialState, (builder) => {
  builder
    .addCase(removeItem, (state, action) => {
      state.wishList = state.wishList.filter((item => item !== action.payload))
    })
    .addCase(addItem, (state, action) => {
      if(state.wishList.length < 10) {
        state.wishList.push(action.payload)
      }
    })    
    .addDefaultCase((state, action) => {});
});

const store = configureStore({
  reducer: {
    cart: wishListReducer,
  },
});

The initial wish list:

const initialState = {
  wishList: [
    "Toy Car",
    "Football"
  ],
};

Considering the initalState and wishListReducer defined above, what is true about wishListReducer?

Sample candidate report

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
