var myarray = ["item 1", "item 2", "item 3", "item 4"];

//removes the first element of the array, and returns that element.
alert(myarray.shift());
//alerts "item 1"

//removes the last element of the array, and returns that element.
alert(myarray.pop());
//alerts "item 4"

This should remove the first element, and then you can return the remaining:

这应该删除第一个元素，然后您可以返回剩余的元素：

var myarray = ["item 1", "item 2", "item 3", "item 4"];
    
myarray.shift();
alert(myarray);

As others have suggested, you could also use slice(1);

正如其他人所建议的，您也可以使用 slice(1);

var myarray = ["item 1", "item 2", "item 3", "item 4"];
  
alert(myarray.slice(1));

Why not use ES6?

为什么不使用 ES6？

 var myarray = ["item 1", "item 2", "item 3", "item 4"];
 const [, ...rest] = myarray;
 console.log(rest)

Try this

尝试这个

    var myarray = ["item 1", "item 2", "item 3", "item 4"];

    //removes the first element of the array, and returns that element apart from item 1.
    myarray.shift(); 
    console.log(myarray);

This can be done in one line with lodash _.tail:

这可以在一行中使用 lodash 完成_.tail：

var arr = ["item 1", "item 2", "item 3", "item 4"];
console.log(_.tail(arr));

You can use array.slice(0,1) // First index is removed and array is returned.

您可以使用 array.slice(0,1) // 删除第一个索引并返回数组。
