为什么不必要的 'else' after 'return' (no-else-return) 错误
Why the Unnecessary 'else' after 'return' (no-else-return) error
我总是使用 else 语句。以及 Data.js 文件中的数据。有什么我可能忽略的吗?
import data from './Data'
function List(props){
const filteredData = data.filter((el) => {
if (props.input === '') {
return el
} else {
return el.text.tiLowerCase().includes(props.input)
}
})
那是 just what the rule requires。
Disallows return before else.
If an if block contains a return statement, the else block becomes unnecessary. Its contents can be placed outside of the block.
如果您认为这条规则值得遵守,请改用(拼写正确)
const filteredData = data.filter((el) => {
if (props.input === '') {
return el
}
return el.text.toLowerCase().includes(props.input)
})
甚至更好
const filteredData = data.filter((el) => {
return props.input === ''
? el
: el.text.toLowerCase().includes(props.input)
})
如果 el
永远是真实的,那么 return true
会更有意义。
const filteredData = data.filter((el) => {
return props.input === ''
? true
: el.text.toLowerCase().includes(props.input)
})
这允许简化为
const filteredData = data.filter((el) => {
return props.input === '' || !el.text.toLowerCase().includes(props.input)
})
