Remove the first element from an array

1. Using shift() method
2. Using slice() method

1. Using shift() method

The shift() method will remove the first element from an array and return that removed element. This method will update the original array.

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

arr.shift(); // item 1
console.log(arr);
// ["item 2", "item 3", "item 4"]

2. Using slice() method

In the second method, we will use the slice() method to return the shallow copy of an array that selected from `start` to `end` index. It doesn’t modify the original array.

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

const newArr = arr.slice(1);
console.log(newArr);
// ["item 2", "item 3", "item 4"]

That’s it for today.
