js最简代码获取多个数组的交集

直接上代码！

//定义三个数组
let a = [1,3,5,7,9];
let b = [1,2,4,5,7];
let c = [1,3,5,8,7];

const getIntersection = (a,...array)=>{ //...array 表示可以传入多个数组
	return a.filter(item=>array.every(elem=>elem.includes(item)))
}
let newArray = getIntersection(a,b,c)
console.log(newArray)
}

代码就不多解释，稍微改一改还能找出多个数组元素值均为对象的的交值
