阿里算法题：编写一个函数计算多个数组的交集

// 多个数组取交集(三个及以上) // 原数组 const serveralArr = [ [1,2,4,5,23,3,2,2,4,3,5,5], [3,2,3,2,2,4,3,1,4,5,6], [3,2,4,3,2,4,1,2,5], [3,2,4,5,5,4,3,1,2,2], [3,2,23,3,4,1,3,4,5,5,4,3,1,2,2], [3,2,4,1,2,5,5,4,3,1,2,2], [3,2,4,25,5,4,3,1,2,2], ] // ES5 方法实现数学意义上的交集结果 const intersectNoRepeatFirst = serveralArr => { let minArr = serveralArr[0] serveralArr.forEach(item...
