在下面的例子中,使用 vue3 的计算属性,我们应该将“computed”放在最外层还是单独对数据进行“computed”?哪个表现更好?
const arr = computed(()=>[
{options:cpuData.map((item)=>({...item,name:'tom'}))},
{options:disData.map((item)=>({...item,name:'jerry'}))},
{options:memoryData.map((item)=>({...item,name:'oh'}))},
{options:testData.map((item)=>({...item,name:'test'}))},
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
])
const arr = [
{options:computed(()=>cpuData.map((item)=>({...item,name:'tom'}))),
{options:computed(()=>disData.map((item)=>({...item,name:'tom'}))),
{options:computed(()=>memoryData.map((item)=>({...item,name:'tom'}))),
{options:computed(()=>testData.map((item)=>({...item,name:'tom'}))),
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
{options:[{name:'test'},{name:'test2'}]},
]
