9/5/2023 0 Comments Js slice arrayThe slice() function provides the ability to shallow copy a portion of the items in an array into a completely new array and return that new array upon function completion. One of those useful functions that will be explored in this article is the slice() function. These functions offer a number of advantages, the most noteworthy of which is the fact that, while at one time in the past developers had to implement their own complex logic to perform various array operations, now the need for such homegrown implementations has been eliminated by all of these new functions. We have implemented a number of scenarios using different approaches and we’ve learned how to slice arrays efficiently.There have been many useful functions that have been added to the Javascript Array global object over the last few years that offer developers a wide variety of options when they are writing code that works with arrays. In this article, we introduced array slicing in C#. But it is not the case when we use it on a Span. One thing worth mentioning is if we use the range operator to work with arrays, it allocates new arrays. We can also see that these boundaries don’t work in the backward direction, so slice5 throws an ArgumentOutOfRangeException. Var slice5 = array // Throws ArgumentOutOfRangeExceptionĪs we see, we can use either, both, or no operands. Var slice3 = array // From the index 1 to index 2 Var slice2 = array // From the start to index 1 Var slice1 = array // From index 2 to the end So let’s import LINQ and consume these two methods: var posts = new string This is known as pagination and is achieved using two LINQ methods Skip() and Take(). Let’s say we have an array of ten posts and we only want to return five of them to the user, with the intention to return the rest of them on demand. Now, let’s jump into code to see how to slice arrays in C# in action.
