从给定对象中获取Array-Object-String [英] get Array-Object-String thing from the given Object

问题描述

我有这样的对象
freq = {a:50，r:25，m:25}

我想将其转换为 Array-Object 之类的东西

I have such an Object
freq = { a: 50, r: 25, m: 25 }

I want to convert it to this Array-Object like thing

dps = [  
   { label: "a",
     y: 50  },
   { label: "r",
     y: 25  },
   { label: "m",
     y: 25  }
];

这是用于创建带有画布的图表.

This is for creating a Chart with canvas.

推荐答案

您可以获取对象的条目并获取

You could take the entries of the object and take a destructuring assignment for the key/value pairs and map new objects with short hand properties.

var freq = { a: 50, r: 25, m: 25 },
    dps = Object.entries(freq).map(([label, y]) => ({ label, y }));
    
console.log(dps);
