在JavaScript中删除数组元素-Delete与Splice

问题：

What is the difference between using the delete operator on the array element as opposed to using the Array.splice method ? 在数组元素上使用delete运算符与使用Array.splice方法有什么Array.splice ？

For example: 例如：

myArray = ['a', 'b', 'c', 'd'];

delete myArray[1];
//  or
myArray.splice (1, 1);

Why even have the splice method if I can delete array elements like I can with objects? 如果可以像删除对象一样删除数组元素，为什么还要使用splice方法？
