Javascript代码的小小疑问11.16——Array.from()

Question

 let obj = ["x","y","z"];  let objTmp = {};   Array.from(obj,(o)=>{     console.log(o+1); });   //x1,y1,z1我想得到如下形式：{x1:'', y1:"",z1:''}, 但不行，How? let obj = ["x","y","z"];  let objTmp = {};   Array.from(obj,(o)=>{     Object.assign(objTmp, o+1); }); console.log( objTmp);   //{"0":z, "1":1}
