js 从目标数组中过滤掉 一个数组元素，
标题描述的有点僵硬，大概需求是，从目标数组中过滤掉我想要删除的元素集合，这里使用的是遍历+过滤器的组合，很方便，做个笔记！
let old = ["AE_CN_SUPER_ECONOMY_G", "CAINIAO_EXPEDITED_ECONOMY", "CAINIAO_SUPER_ECONOMY_SG", "CAINIAO_SUPER_ECONOMY", "SINOTRANS_PY", "SUNYOU_ECONOMY", "YANWEN_ECONOMY", "SGP_OMP", "YANWEN_JYT", "SF_EPARCEL_OM", "CAINIAO_ECONOMY", "CAINIAO_ECONOMY_SG", "CAINIAO_STANDARD", "CAINIAO_STATION", "AE_CAINIAO_STANDARD", "CAINIAO_STANDARD_HEAVY", "CAINIAO_STANDARD_SG", "YANWEN_AM", "SGP", "CPAM", "EMS_ZX_ZX_US", "CAINIAO_PREMIUM"]; let del = ["SGP_OMP", "YANWEN_JYT", "SF_EPARCEL_OM", "CAINIAO_ECONOMY", "CAINIAO_ECONOMY_SG", "CAINIAO_STANDARD", "CAINIAO_STATION", "AE_CAINIAO_STANDARD"] // let newList = [];//空容器 del.forEach((item)=>{ //遍历每个要删除的元素 1 old = old.filter((currentValue)=>{ //定义一个过滤器，过滤器过滤掉有当前循环的值 return currentValue !== item; }) console.log("过滤过的新数组",old) })
