for(var i = 0; i < arrKey.length; i++){

用json来存，如var obj={}，obj[i].key='key',obj[i].value='value'

function makeObject(keys, values) {
    let obj = {};
    
    keys.forEach((key, index) => {
        obj[key] = values[index];
    });
    
    return obj;
}

var keys=['k1','k2','k3'],values=['v1','v2','v3'];
var obj={};
for(var i=0;i<keys.length;i++){
   obj[keys[i]]=values[i]
}
console.log(obj);

const ArraytoObj = (keys = [], values = []) => {
  if(keys.length === 0 || values.length === 0) return {}
  const len = keys.length > values.length ? values.length : keys.length
  // if you want save all the keys, and the value could be undefined, you can use keys.forEach function instead of for loop
  const obj = {}
  for(let i = 0; i < len; ++i) {
    obj[keys[i]] = values[i]
  }
    return obj
}
