Note that these methods all mutate the original array.Ozone Elements Mastering Software Plug-In splice() changes an array by replacing the values. push() adds one or more values at the end of an array, while unshift() adds them at the beginning. The pop() method removes the last item from an array, while shift() removes the first. In the following example, splice() will replace the value at index 0 (the beginning of the array) with another single value: const numbers = Ĭonsole.log(numbers) // Summary You can also replace a value with another value. The following example shows splice() inserting an item at index 2 (that is, the third spot): const numbers = Ĭonsole.log(numbers) // You can use splice() to insert a value inside an array or to replace a value with another value. In this example, unshift() adds two names at the beginning of the array: const people = Ĭonst count = people.unshift('akilah', 'isaac')Ĭonsole.log(people) // Remove and Replace Items With splice() This is the opposite of push(), which inserts the values at the end. The unshift() method add one or more values to the beginning of an array and returns the length of the array. Add One or More Items to the Beginning of an Array With unshift() As a result, the original array is mutated. When shift() is called on the people array, the first value in the array is removed and assigned to firstPerson. This method's behaviour is the direct opposite of the pop() method. The shift() method removes the first value from an array and returns that value. The push() method adds one or more items at the end of an array and returns the length of the array.įor example, let's add two more names to the people array with push(): const people = Ĭonst count = people.push('akilah', 'isaac')Ĭonsole.log(people) // Remove the First Value From an Array With shift() Add One or More Items to the End of an Array With push() The original array ( people) is also mutated. When pop() is called on the people array, the last value in the array is removed and assigned to lastPerson. The pop() method removes the last value from an array and returns that value. Remove the Last Item From an Array With pop()
Specifically, let's take a look at the methods responsible for inserting items into an array and removing items from an array. We can also use the includes() method to check if a value exists in an array: const people = Ĭonsole.log(people.includes('sam')) // trueĬonsole.log(people.includes('jack')) // false For example, we can reverse an array using the reverse() method as follows: const people = You can manipulate or get information about an array using array methods. Values can also be of any data type, including number, boolean, and even another array. The values can be strings: const people = MethodĪn array is a special variable that can hold more than one value at a time. Click on the method name to jump to the description below. Here's a quick reference table for the different array methods that let you add or remove items. In this article, we'll take a look at various ways to add and remove elements from an array in JavaScript.
