Today, I wanted to talk about the Array.shift()
method. This is a quick one.
The 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[0];
The Array.shift()
method is most useful when you want to actually remove the first item from the original array and modify its length.
