Remove the first element from an array
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.
1 2 3 4 5 | 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.
1 2 3 4 5 | 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.
