A stack is a fundamental data structure. It is linear and pursues a specific sequence in performing the operations. In a stack, deletion and insertion of items can occur only at one end, and that is top of the stack. Think of it as a pile of bricks where you can only take the topmost brick off in order to remove things from it. Similarly, the addition of brick also occurs on the top. Programming uses this stack structure throughout. The term stack gained popularity through the LAMP stack.
Today’s web solutions are complex and need to be constantly altered and upgraded to meet user demands. Hence, the stack has also evolved to accommodate the same. MERN and MEAN are the two popular stacks used by web developers all over the world. These stand for –
**MERN: **MongoDB, ExpressJS, ReactJS, NodeJS
**MEAN: **MongoDB, ExpressJS, AngularJS, NodeJS
The main benefits of MEARN are:
MEAN is one of the fastest growing combinations of technologies. Equipped with responsive tools and plugins, MEAN reduces the time spent on managing the systems. Some of the most complex websites and application built today use it for faster deployment.
The main benefits of MEAN are:
The main difference between MERN and MEAN boils down to the choice between React or Angular. React framework is lightweight and specifically designed for seamless development of web user interfaces which are either single or multi-page and hybrid. As against this, Angular is mostly used in Single Page Applications (SPA) to deliver unbroken and smooth user experience as it sanctions rendering the complete page without the need to refresh it.
MEAN has been in the market far longer than MERN but MERN is slowly picking up in popularity. Both MERN and MEAN are sound and viable options. However, the final choice should depend upon the demands of the project and the application developer’s familiarity with the technologies involved. Since both are open source and use almost the same technology combination, it is a matter of deciding between React and Angular.

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.
To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.
Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Let me show what I mean…
There are template parser errors that can be easy catched by stackblitz
It gives me some information but I want the error to be highlighted

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 the midst of this pandemic, what is allowing us unprecedented flexibility in making faster technological advancements is the availability of various competent cloud computing systems. From delivering on-demand computing services for applications, processing and storage, now is the time to make the best use of public cloud providers. What’s more, with easy scalability there are no geographical restrictions either.
Machine Learning systems can be indefinitely supported by them as they are open-sourced and within reach now more than ever with increased affordability for businesses. In fact, public cloud providers are increasingly helpful in building Machine Learning models. So, the question that arises for us is – what are the possibilities for using them for deployment as well?
Model building is very much like the process of designing any product. From ideation and data preparation to prototyping and testing. Deployment basically is the actionable point of the whole process, which means that we use the already trained model and make its predictions available to users or other systems in an automated, reproducible and auditable manner.
