How to get something from the state or store inside a React Redux-Saga function?

To get something from the state or store inside a React Redux-Saga function, we call the select function.

For instance, we write

export const getProject = (state) => state.project;

// Saga
export function* saveProjectTask() {
  while (true) {
    yield take(SAVE_PROJECT);
    let project = yield select(getProject);
    yield call(fetch, "/api/project", { body: project, method: "PUT" });
    yield put({ type: SAVE_PROJECT_SUCCESS });
  }
}

to call select with the getProject to get the project state from the store.
