js怎么把有逗号分隔的内容分开并放在数组里

比如我有一组数据，每组数据都有逗号分隔：防火墙、安全服务、安全机制,创造、虚幻、虚拟,1,1,1,1,1
怎么把他变成常规文字，并装在数组里，大致效果就是：data = {"防火墙、安全服务、安全机制","创造、虚幻、虚拟","1","1","1","1","1"}

 
    var s = '防火墙、安全服务、安全机制,创造、虚幻、虚拟,1,1,1,1,1';
    var arr = s.split(',');//split，用指定字符拆成数组就行
    console.log(JSON.stringify(arr))//["防火墙、安全服务、安全机制","创造、虚幻、虚拟","1","1","1","1","1"]
    console.log(arr[0])//防火墙、安全服务、安全机制
    console.log(arr[1])//创造、虚幻、虚拟

const str='1,2,3,4'
const  data =  str.split(',')
