大佬们遇到过这个问题吗？js数组间循环添加问题?十分感谢

Question

1.元数据constarr1=["#355b54","#12d806","#748aac"];constarr2=[{type:"一类"},{type:"二类"},{type:"三类"},{type:"四类"},{type:"五类"},{type:"六类"},{type:"七类"},{type:"其他"}];2.需要将arr中数据按照索引插入到arr2,arr1商量继续从arr[0]添加.3.最后的效果是这样:constarr=[{type:"一类",color:"#355b54"},{type:"二类",color:"#12d806"},{type:"三类",color:"#748aac"},{type:"四类",color:"#355b54"},{type:"五类",color:"#12d806"},{type:"六类",color:"#748aac"},{type:"七类",color:"#355b54"},{type:"其他",color:"#12d806"}]

Answer 1

constarr=arr2.map((item,index)=>({
...item,
color:arr1[index%arr1.length]
}))
                            

Answer 2

letarr1Length=arr1.length
letresult=arr2.map((item,index)=>{
letidx=index%arr1Length//取余，首尾循环
return{...item,color:arr1[idx]}
})
console.log(result)
