<h1>JavaScript Stable Sort</h1>

<p>From ES2019, browsers must use a stable sorting algorithm.</p>

<p>When sorting elements on a key, the elements must keep their relative position to other objects with the same key.</p>

const myArr = [

{name:"X00",price:100 },

{name:"X01",price:100 },

{name:"X02",price:100 },

{name:"X03",price:100 },

{name:"X04",price:110 },

{name:"X05",price:110 },

{name:"X06",price:110 },

{name:"X07",price:110 },

{name:"X08",price:120 },

{name:"X09",price:120 },

{name:"X10",price:120 },
