在Javascript中将2元素列表转换为dict

function convertToDict(keys, values) {
  var dict = {};
  for (var i = 0; i < keys.length; i++) {
    dict[keys[i]] = values[i];
  }
  return dict;
}

var keys = ['key1', 'key2'];
var values = ['value1', 'value2'];
var dict = convertToDict(keys, values);
console.log(dict);

function convertToDict(keys, values) {
  return keys.reduce(function(dict, key, index) {
    dict[key] = values[index];
    return dict;
  }, {});
}

var keys = ['key1', 'key2'];
var values = ['value1', 'value2'];
var dict = convertToDict(keys, values);
console.log(dict);
