谈谈JavaScript Array filter() 方法

let markPointData = op.series[params.seriesIndex].markPoint.data;
let newMarkPointData = markPointData.filter(({ name }) => name !== params.name);

d1 = dataset[selected[0].seriesName];
let ptr = selected[0].dataIndex;
// 从一个数组中删除另一个数组中存在的元素
new_d1 = d1.filter((items) => !ptr.some((item) => d1.indexOf(items) === item));
