In this tutorial, we will try to get the last element in an array using the following three approaches − Using Array length Property. Using the slice() Method. Using the pop() Method. Using Array length Property The length property of an array returns the number of elements in an array. The array index will start from 0, and the last index will total the length of array -1. For example, if the length of the array is 5 the indexing numbering will be 0 to 4. That means if we want to get the last element, the index ... Read More
This tutorial will discuss how to write swift program to get the size of set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To get the size of a Set Swift provide an in-built property named count. It will return the total number of elements present in the specified count. Below is a demonstration of the same − Input Suppose our given input is − MySet ... Read More
In this tutorial, we will look at a few ways to print a number with commas as thousands of separators in JavaScript and compare them to understand which one is suitable in a given context. Why do we do number formatting? In English, commas are used to separate numbers bigger than 999. Dot is the thousands separator in Germany. Sweden uses space. The separator is added after every three digits from the right. Let’s briefly introduce the methods. Using the toLocaleString() Method Here, the built-in locale string method localizes the number format based on the country. ... Read More
In this tutorial, we will look at the method to preserve variables in a JavaScript closure function. What is a closure function? A closure function gives access to the scope of an outer function from an inner function. It also allows private variables. Closure variables are stored in stack and heap. When a function is created, closure is also created. Closure remembers external things used in it. Closures are the primary mechanism for data privacy. One drawback is that the variables used are not garbage collected. Overuse of closure functions will damage the system due to redundant ... Read More
In this tutorial, we will learn to make a text italic using JavaScript. We give the italic property to a text to differentiate it from other text within the sentence. In HTML, we can make a text italic by just adding the text within the 'i' tag. But sometimes, we have to make it dynamic, that not possible with HTML. Then, we have to use a programming language like JavaScript to make the text italic. Let's have a look at how to make a text italic using JavaScript. Following are the ways by which we can make a ...

Introduction Citrix's XenServer and VMware's vSphere are server virtualization platforms. Server virtualization is the process of partitioning a physical server into multiple unique and isolated virtual servers. Every virtual server can independently run its own operating system. To hide server resources from server users, server virtualization is utilized. This includes different OSs, CPUs, Processors, etc. The idea of server virtualization is frequently used in IT infrastructure to reduce costs by making better use of already available resources. What is Citrix XenServer? XenServer is an open-sourced product from Citrix. It's a platform for bare metal (type-1 hypervisor) server virtualization. Which can ... Read More
Beforehand cloud computing, associations expected to store all their data and programming on their hard drives and servers. The more prominent the association, the more servers they required. This way of dealing with treating data isn't versatile at speed. Cloud progression proposes that affiliations can scale and change at speed and scale, speed up progress, drive business, smooth out works, and decrease costs. Cloud computing is critical because it offers versatility, data recovery, zero upkeep, basic access, and a higher degree of well-being. Cloud Computing Definition In Cloud computing, Cloud implies the "servers" that are gotten to over the web ... Read More

Machine learning is a subfield of artificial intelligence (AI) and computer science that focuses on using data and algorithms to mimic human learning processes and progressively increase accuracy. The developing discipline of data science heavily relies on machine learning. In data mining projects, algorithms are taught to generate classifications or predictions using statistical approaches, revealing important insights. These insights then influence decision-making within applications and enterprises, perhaps impacting significant growth KPIs. Big data's continued growth and expansion will drive up demand for data scientists, who will be needed to help identify the most important business issues and the data needed ... Read More
