如何将数组转换为对象

var arr = ['name', 'John', 'age', 25];
var obj = {};

for (var i = 0; i < arr.length; i += 2) {
  obj[arr[i]] = arr[i + 1];
}

console.log(obj);

var arr = ['name', 'John', 'age', 25];

var obj = arr.reduce(function(result, current, index, array) {
  if (index % 2 === 0) {
    result[current] = array[index + 1];
  }
  return result;
}, {});

console.log(obj);

var arr = [['name', 'John'], ['age', 25]];

var obj = Object.fromEntries(arr);

console.log(obj);
