布尔方法的返回值

Question

当consignmenttypeName为库存或寄售时，我想返回true，否则返回false。这是我的代码。

<template>
  <div class="modal fade bd-example-modal-xl" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-xl modal-dialog-centered" role="document">
  <div class="modal-content">

    <div class="modal-header">
      <h5 class="modal-title" id="exampleModalLabel">The title</h5>
      <button type="button" class="close" data-dismiss="modal" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
    </div>
    <div class="modal-body">
      <h2>{{ modalData.projectName }}</h2>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        </div>
      </div>
    </div>
  </div>
</template>

<script>

export default{
   name: "modalBlock",
   props:['modalData'],
   data(){
      return {
      }
   },
   methods: {
  close() {
     this.$emit('close');
  },
  }
 }

</script>

此代码是否存在任何错误。当consignmenttypeName不等于库存或寄售时，此代码返回false吗？
