function selectedSubreddit(state = 'reactjs', action) { switch (action.type) { case 'tr': return '突然' default: return state }}var a1 = { type: 'tr'}let selected = selectedSubreddit(,a1);console.log(selected);function selectedSubreddit(action,state = 'reactjs') { switch (action.type) { case 'tr': return '突然' default: return state }}var a1 = { type: 'tr'}let selected = selectedSubreddit(a1, );console.log(selected); // 突然
