更改从数组的元素赋值的变量时,数组中的特定元素将随变量而变化。但是,代码中没有要更改的数组。在代码中,数组是一个对象数组,变量在函数 randomCentroid(质心)内声明和赋值,该函数在初始化质心中调用。该代码用于生成有关 k 均值聚类的随机质心,因此代码://Return random centroid points with coloringlet randomCentroid = (fill) => { let r = Math.floor(Math.random()*points.length); let centroid = points[r]; //points.splice(r, 1); centroid.fill = fill; return centroid;}//Gives distinct coloring to all centroid pointslet initializeCentroids = (num) => { let allCentroids = []; for (let i = 0; i < num; i++) { let color = colors(i); let centroid = randomCentroid(color); centroid.id = 'centroid' + '-' + i; allCentroids.push(centroid); } return allCentroids;}//same for const.let points = [{}, {}, {}, {}, {}], colors = d3.scaleOrdinal(d3.schemeCategory10);initializeCentroids(3);console.log(points);安慰:索引.js:29(5) [{...}, {...}, {...}, {...}, {...}]0: {填充: “#2ca02c”, id: “质心-2”}1: {}2: {填充: “#ff7f0e”, id: “质心-1”}3: {填充: “#1f77b4”, id: “质心-0”}4: {}长度: 5原型: 数组(0)如何删除由数组分配的对象组成的变量与数组之间的依赖关系?
