将字符串数组转换为Object Javascript

function arrayToObject(arr, delimiter) {
  var obj = {};
  for (var i = 0; i < arr.length; i++) {
    var keyValue = arr[i].split(delimiter);
    obj[keyValue[0]] = keyValue[1];
  }
  return obj;
}

var arr = ["key1:value1", "key2:value2", "key3:value3"];
var obj = arrayToObject(arr, ":");
console.log(obj);

function arrayToObject(arr, delimiter) {
  return arr.reduce(function(obj, str) {
    var keyValue = str.split(delimiter);
    obj[keyValue[0]] = keyValue[1];
    return obj;
  }, {});
}

var arr = ["key1:value1", "key2:value2", "key3:value3"];
var obj = arrayToObject(arr, ":");
console.log(obj);
