如何将函数转换为es6箭头函数

Question

我需要使用ES 6将以下功能写入箭头功能。下面我给了function.in reactjs

//

        tab_Row(){
          return this.state.business.map(function(object, i){
              return <Table_Row  />;
          });
        }

Answer 1

您可以这样-

 tab_Row = () => {
          return this.state.business.map((object, i) => {
              return <Table_Row  />;
          });
        }

Answer 2

您可以像这样为上述代码编写ES-6语法

 const tab_Row = () => {
          return this.state.business.map((object, i) => {
              return <Table_Row  />;
          });
        }

Answer 3

您无法弄清楚的问题到底是什么？

   tab_Row = () => {
          return this.state.business.map((object, i) => {
              return <Table_Row  />;
          });
        }
