注释语句：

<div>{/* 这个是注释的代码 */}</div>

逻辑判断

const btnType = 'primary';
const count = 3;
<Button type={count > 1 ? btnType : 'text'}>btn</Button>;

const count = 9;
<div>{count > 1 ? <p id="3">1111</p> : <h1 className="4">2222</h1>}</div>;

const count = [1, 2, 3];
<div>{count.length ? <p id="3">1111</p> : <h1 className="4">2222</h1>}</div>;

• 模版字符串

const w = 50;
return (
  <div
    style={{
      width: `${60 + w}px`
    }}
  >
    cube
  </div>
);

• 函数

const caclWidth = (v1, v2) => {
  return `${v1 + v2 + 20}px`;
};
return (
  <div
    style={{
      width: caclWidth(2, 3)
    }}
  >
    cube
