vue/return-in-computed-property Enforce that a return statement is present in computed property

此规则强制return语句在computed属性中得完整存在。

<script>
export default {
  computed: {
    /* ✓ GOOD */
    foo () {
      if (this.bar) {
        return this.baz
      } else {
        return this.baf
      }
    },
    bar: function () {
      return false
    },
    /* ✗ BAD */
    baz () {
      if (this.baf) {
        return this.baf
      }
    },
    baf: function () {}
  }
}
</script>
