怎么让ie兼容es6，ie兼容ES6的方法，包括箭头函数

如下示例：使用es6语法

<script type="text/babel">
const arr1=[1,2,3]
const arr2=[...arr1]
console.log(arr2);
let arr3=arr2.map((x)=>x*2)
console.log(arr3);
const [x,y,z]=[[...arr3]]
console.log(x);

class Point {
constructor(x, y) {
this.x = x;
this.y = y;
}

toString() {
return '(' + this.x + ', ' + this.y + ')';
}
}
console.log(new Point(1, 2).toString());
</script>
<script src="browser.min.js"></script>

<script>

index.js:4 [1, 2, 3]
index.js:5 [2, 4, 6]
index.js:7 [2, 4, 6]
index.js:20 (1, 2)
