Today, I wanted to talk about the
Array.shift() method. This is a quick one.
Array.shift() method removes the first item from an array and returns it. The array is modified.
let wizards = ['Gandalf', 'Radagast', 'Merlin']; let first = wizards.shift(); // logs "Gandalf" console.log(first); // logs ["Radagast", "Merlin"] console.log(wizards);
If you only need to get the first item in the array, you’re probably better off using bracket notation, like this.
let first = wizards;
Array.shift() method is most useful when you want to actually remove the first item from the original array and modify its length.
