javascript - 组件的条件渲染

问题描述

我试图仅在asset.id === collection.masterAssetId. 如果是这种情况，应该会出现一个星形图标。我正在使用该getMasterId功能来检查这种情况。有谁知道这里的错误是什么？

错误：

Parsing error: Unexpected token

  70 |                     
  71 |                     {
> 72 |                       if(asset.id === this.getMasterId(asset.id)){
     |                       ^
  73 |                       <FaStar />
  74 |                     }}

应用程序.js

import './App.css';
import {collections} from "./data.js"
import {assets} from "./data.js"

           assetsarr: assets,
           clickedassets: []
        }
    }

    getMasterId(assetnr){
      const assetnum = this.state.collectionsarr.find(element => element.masterAssetId === assetnr).masterAssetId
      return assetnum
    }
  
  render(){
  return (
          <div className="App">

                    <br></br>
                  </div>
