Try this
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 should remove the first element, and then you can return the remaining:
var myarray = ["item 1", "item 2", "item 3", "item 4"];
myarray.shift();
alert(myarray);
As others have suggested, you could also use slice(1);
var myarray = ["item 1", "item 2", "item 3", "item 4"];
alert(myarray.slice(1));
This can be done in one line with lodash _.tail:
var arr = ["item 1", "item 2", "item 3", "item 4"];
console.log(_.tail(arr));

Why not use ES6?
var myarray = ["item 1", "item 2", "item 3", "item 4"];
const [, ...rest] = myarray;
console.log(rest)
You can use array.slice(0,1) // First index is removed and array is returned.
