数组合并方法

Question

vararr1=['name','age','home']vararr2=[['a','b','c','d','e'],[1,2,3,4,5],['one','two','three','four','five']]vararr3=[{'name':'a','age':1,'home':'one'},{'name':'b','age':2,'home':'two'},{'name':'c','age':3,'home':'three'},{'name':'d','age':4,'home':'four'},{'name':'e','age':5,'home':'five'}];已知数组1和2，求写一种方法得到数组3的形式

Answer 1

functiontrans(names,arr){
letresult=[]
for(leti=0,len=arr[0].length;iletobj={}
names.forEach((name,index)=>{
obj[name]=arr[index][i]
})
result.push(obj)
}
returnresult
}
vararr1=['name','age','home']
vararr2=[['a','b','c','d','e'],[1,2,3,4,5],['one','two','three','four','five']]
trans(arr1,arr2)
                            

Answer 2

vararr1=['name','age','home']vararr2=[['a','b','c','d','e'],[1,2,3,4,5],['one','two','three','four','five']]arr2[0].map((item,index)=>{
returnarr1.reduce((a,b,i)=>(a[b]=arr2[i][index],a),{})
})
