The syntax for splice is slightly more complex: array. The splice method in JavaScript is like a kitchen tool that lets you cut, chop, and mix ingredients to create a whole new dish. Now you can work with the youngestAges array without affecting the original ages array.
If you want to find out the ages of the three youngest people in the class, you can use slice to create a new array containing just those elements: const youngestAges = ages. This is useful when you need to work with a specific subset of elements from an array, but you don't want to affect the original array.įor example, let's say you have an array of numbers representing the ages of people in a class: const ages = Use slice when you want to create a new array that contains a subset of elements from an existing array, without modifying the original array. The original fruits array remains unchanged, and we can now work with the slicedFruits array however we like! When to Use Slice In this example, slice is used to create a new array called slicedFruits, which contains elements from index 1 (inclusive) to index 4 (exclusive) of the fruits array. const fruits = const slicedFruits = fruits. You specify the starting and ending indexes of the array subset you want to keep, and slice creates a new array containing those elements, leaving the original array untouched. The syntax for the slice method is straightforward: array. The best part about this method is that the original array remains unscathed! The slice method in JavaScript is like a virtual knife that lets you cut a new array out of an existing one.
#JAVASCRIPT ARRAY SPLICE VS SLICE HOW TO#
In this article, we'll explore the differences between slice and splice, and provide you with some exciting code examples to help you understand how to use them properly. JavaScript is a versatile language for web development, and it offers several powerful methods for working with arrays, such as slice and splice.Īt first glance, these methods might seem interchangeable, but they actually have distinct differences that can impact your code.
