In this article, we will learn about comparing Difference between localStorage and sessionStorage. Websites hosted on a browser have no capacity of having any memory to store user's data. A user visiting from one page to another page on a website will be treated as a new user every time. The browser provides different types of storage mechanisms (localStorage, sessionStorage, cookies) to overcome this issue. Storage mechanism enables the website you are visiting to keep track of your movement from one page to another page so that the same information doesn't get asked which is already given to the website.
localStorage, sessionStorage, and cookies are all client storage solutions that store in a single file in the user's system. Session data is stored on the server where the application/website is hosted. localStorage and sessionStorage, part of the web storage API, are two awesome tools to save the data in format of key/value pairs locally.
In this article, We will try to understand the difference between localStorage and sessionStorage.
It is a type of web storage that allows websites/applications to store and access data in the browser with no expiration date. This means the data stored in the browser will persist even after the browser window has been closed.
// Save data to localStorage localStorage.setItem('key', 'Value'); // Get saved data from localStorage let lastname = localStorage.getItem('key'); // Remove saved data from localStorage localStorage.removeItem('key'); // Remove all saved data from localStorage localStorage.clear();
The sessionStorage object stores data for only one session, Meaning the data is deleted when the browser tab is closed.
// Save data to sessionStorage sessionStorage.setItem('key', 'value'); // Get saved data from sessionStorage let lastname = sessionStorage.getItem('key'); // Remove saved data from sessionStorage sessionStorage.removeItem('key'); // Remove all saved data from sessionStorage sessionStorage.clear();
localStorage and sessionStorage are performing similar tasks but with some very basic differences.

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

In this video you will learn the difference between waterfall and agile model, what is lean, lean vs agile vs waterfall differences in detail.
Why DevOps is important?
DevOps implementation is going through the roof with most of the largest software organizations around the world invested heavily in its implementation. The core values of devops is effectively based on the Agile Manifesto but with one slight change which moves the focus from creating a working software to one that is more interested in the end-to-end software service mechanism and delivery.

Every year, the world is expanding with the launch of new smartphones and other gadgets available in the market. According to Statista, more than 50% of the population will be using smartphones by the end of 2021.
Hence, businesses worldwide have understood the importance of smartphones and are joining the mobile industry by launching native apps.
Apart from native apps, progressive web apps is another technology that is gaining a lot of attention among businesses. Moreover, various leading companies worldwide have openly accepted PWA and built progressive web apps.
Now, the question arises, how is PWA different from the native apps? Read More

In this video on Hadoop vs Spark you will understand about the top Big Data solutions used in the IT industry, and which one should you use for better performance. So in this Hadoop MapReduce vs Spark comparison some important parameters have been taken into consideration to tell you the difference between Hadoop and Spark also which one is preferred over the other in certain aspects in detail.
Why Hadoop is important
Big data hadoop is one of the best technological advances that is finding increased applications for big data and in a lot of industry domains. Data is being generated hugely in each and every industry domain and to process and distribute effectively hadoop is being deployed everywhere and in every industry.

If you are an entrepreneur or an enterprise IT leader, then you need to plan the technology stack for your software development project. You need to choose the right database for your project. If you are developing a heavy-duty transaction processing system or a high-demand analytics system, you will likely use an RDBMS (Relational Database Management System). You can choose one from several popular RDBMSs.
However, do you want an assurance that your data in an RDBMS will survive even large-scale failures in application systems and servers? This narrows the choice. This is where CockroachDB becomes important. This relatively new RDBMS offers a high degree of survivability to your data. In this article, we review CockroachDB and its features. We assess its pros and cons. Subsequently, we review its use cases. Finally, we compare CockroachDB with some of the popular databases. Read on.
