es6 过滤

1、通过ES6中的键过滤对象属性

 

      const raw = {

        item1: { key: "sdfd", value: "sdfd" },

        item2: { key: "sdfd", value: "sdfd" },

        item3: { key: "sdfd", value: "sdfd" }

      };

      const allowed = ["item1", "item3"];

      const filtered = Object.keys(raw)

        .filter(key => allowed.includes(key))

        .reduce((obj, key) => {

          obj[key] = raw[key];

          return obj;

        }, {});

      console.log(filtered);

      /**

       *item1: { key: 'sdfd', value:'sdfd' },

       *item3: { key: 'sdfd', value:'sdfd' }
