if you use the trinomial operator in a project, eslint will report an error. How else can this trinomial operation be written?
data () {
return {
open: false,
currentTab: false,
isFolder: this.model.children && this.model.children.length ? true : false
}
},well, if you need a Boolean value, there is no need for trinomial operation to achieve the effect
data () {
return {
open: false,
currentTab: false,
isFolder: this.model.children && this.model.children.length // true or false
}
}
if you must use it
data () {
return {
open: false,
currentTab: false,
isFolder: (this.model.children && this.model.children.length) ? true : false
}
}
add that the operation priority of & & is lower than that of ?: , and the length attribute on the right is not the bool expression
.
then you can turn this off in .eslintrc.js and you will not make a mistake
feel that it will be better to write this into the calculation attribute
