What did you expect to happen?
v-else-if directive , 可以使用数组indexOf或者includes判断元素是否存在， 而不是必须连续使用几个或等于

What actually happened? Please include the actual, raw output from ESLint.
[vue/valid-v-else-if]
'v-else-if' directives require that attribute value.eslint-plugin-vue

[rasca]

This just happened to me.

The error was: 'v-if' directives require that attribute value.eslint(vue/valid-v-if)

The offending line: v-if="item.properties.new !== {} && ['transfers_disabled', 'paused'].some(val => item.properties.new.includes(val)"

Notice it's missing a final ending parenthesis. I believe the error message could be better.

+1 for a better error message. Something like "syntax error in v-if conditional"
