Programming Trends 2022 – How Smart Technology Is Changing Lives



Technology is advancing in leaps and bounds and suddenly what used to be the most common ceases to be. You stay outside, overwhelmed. For this reason, it is important to be attentive when spotting the trends that will lead us into the future of software development.

A good example that the computer world is advancing with great speed and firm steps is the appearance of new programming languages, this last year 2021 has been obtained a preamble of certain technological innovations that open new horizons in programming.

Among the most significant news was without a doubt that of the facebook metaverse, however, what is the metaverse? It is the virtual universe of the future, in which we can interact with other people, buy, move and discover new environments, all through an avatar.

Generally speaking, the metaverse consists of a virtual world accessible via a virtual reality viewer. Eventually, this “access” will be via 3D avatars and will connect different digital environments.

For now, the metaverse is just an idea. It will be the result of the convergence of existing and emerging technologies. Metaverso will be a virtual world, in terms of programming it will be the evolution of the current internet, towards web 3.0 powered by immersive technologies such as virtual reality and augmented reality, it is something of great interest because it ‘is related to what is Information technology has experienced strong growth in recent years and will continue to do so in 2022 and that is artificial intelligence.

When we talk about Web 3.0 technology we are referring to various technologies, with an emphasis on decentralization, the web currently has a hierarchical and centralized organization, but with the emergence of distributed ledger technologies which are essentially digital databases without a central administrator that are synchronized and distributed across different sites, whether institutions or countries, like blockchain, user data can be decentralized and more secure. With a decentralized infrastructure, web 3.0 will enable the creation of peer-to-peer (P2P) connections, which can potentially reduce the power of large tech companies that monopolize and profit from user data.

Machine learning is a method of data analysis that automates the construction of analytical models. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns, and make decisions with minimal human intervention. A practical example is that by using Tensorflow.js and Angular, we can identify faces and interact in certain ways. easy through the browser.

Machine learning is a scientific discipline in the field of artificial intelligence that creates systems that learn automatically. Learning in this context means identifying complex patterns in millions of pieces of data. The Real Learning Machine is an algorithm that examines data and is able to predict future behavior. Automatically, also in this context, implies that these systems are improved autonomously over time

The Blockchain, which to some continues to resemble the cryptocurrency hype, has a large number of uses to develop distributed applications without depending on a central authority. Not just monetary transactions, but smart contracts or authority checks.

Smart contracts are computer programs that execute agreements made between two or more parties when a preprogrammed condition occurs. In other words, they are contracts that are executed and executed automatically and autonomously.


Solidity is a high level programming language whose synthesis is similar to another of the programming languages ​​most used today: Javascript, this language is object oriented (OO) like C ++ and C #.

This language is designed and compiled in bytecode (bytecode) to create and develop smart contracts that run on the Ethereum virtual machine. Solidity is a high level programming language called the “Turing Complete” language.

This concept, imagined by Alan Turing, refers in computer science to this language which has a computing power equivalent to what is called a “Universal Turing Machine”.

The Ethereum Virtual Machine (EVM) is considered a Turing Universal Machine, a term that refers to software that is sufficiently adept at running any code defined by the developer.

It is important to take into consideration that this programming language was specifically designed to develop applications for the Ethereum network. It therefore only works on the Ethereum blockchain or compatible derivatives. One of its advantages is that the source code of the programs created with it is publicly accessible from the blockchain. Even being in bytecode, it is possible to decompile it and get a fairly clear sample of the original source code. Solidity supports inheritance and multiple inheritance, giving it great flexibility when programming complex elements. This language also provides a number of very useful libraries. useful tools that make it easier to program smart contracts, making code reusable and easier to maintain.

Do not give

It is a cross-platform runtime environment for the JavaScript-based server layer.

Node.js is an event scope designed to build scalable applications, allowing you to establish and manage multiple connections at the same time. With this feature, you don’t have to worry about stalling processes because there are no locks, and you don’t have to worry about learning either since you can teach the node to. start from nothing

Node.js has grown rapidly in recent years. This is thanks to the list of features that Easy – Node.js offers, which is quite easy to get started. It is an option for those new to web development. With tons of tutorials and a great community, getting started is a snap.

Node is scalable because it offers great scalability for applications. Node.js, being single threaded, is able to handle a large number of simultaneous connections with high performance. In addition to its speed, non-blocking thread execution makes Node.js even faster and more efficient.

There is a huge set of open source Node.js packages that can simplify your job. There are currently over a million packages in the NPM ecosystem, Node.js is written in C and C ++ which makes it fast and adds features like network support. Cross-platform support lets you build SaaS websites, desktop apps, and even mobile apps, all using Node.js.


Among the NoSQL databases, one of the most famous is probably MongoDB. With a concept very different from relational databases, it becomes an interesting alternative.

MongoDB is a document-oriented database. This means that instead of saving the data in records, you save the data in documents. These documents are stored in BSON, which is a binary representation of JSON. If you want to learn how to program in Mongo from scratch, remember that you can do it easily and at no cost.

MongoDB is written in C ++, although requests are made by passing JSON objects as parameters. This is quite logical, since the documents themselves are stored in BSON.

Although it is often said that NoSQL databases are narrow in scope, MongoDB can be used in many projects that we are developing today.

Any application that needs to store semi-structured data can use MongoDB. This is the case with typical CRUD applications or many current web developments.


angular course

It is an open source software engineering framework used to build single page web applications. Developers also use it to create animated menus for HTML web pages.

The framework is the brainchild of Google engineers Misko Hevery and Adam Abrons. Google officially released the first version, AngularJS, in 2012, and has maintained it ever since.

Angular completely separates the frontend and the backend in the application, avoids writing repetitive code and keeps everything tidier thanks to its MVC (Model-View-Controller) pattern ensuring rapid development, while allowing modifications and updates. up to date.

Programming in Angular is done using TypeScript, a language which is a superset of JavaScript that adds static typing capabilities. This gives us the advantage of being able to type things like variables, functions, returns, as well as being able to create interfaces. TypeScript also gives us the ability to use enumerators, modules, namespaces, decorators, and generics. And finally, the import system, which we will use on a daily basis to atomize and modularize all our code. You can start your learning journey with Angular from scratch.

Angular is undoubtedly becoming more and more of a Roman Empire every day and since its launch it has been constantly updated which brings great interesting challenges and of course constant improvements in the working environments.

Io socket

Last but not least and which is booming is Socket io. is a library Open source of Javascript based on the Websocket protocol for Node.js which enables real-time two-way TCP communication between clients and servers. For this, it relies mainly on Websocket but you can also use other alternatives like taken Adobe Flash, JSONP Query, or AJAX Long Query, selecting the best alternative for the client right at runtime.

Io socket. It is an open source library with a large community that will help us build applications with a persistent connection between client and server. So we will have libraries for each side.

It is developed entirely in Javascript and its goal is to create real-time applications capable of running in any browser, including mobile devices, bridging the differences between different protocols.

If you want to learn how to program, remember that you can find content that is relevant, practical, free, and interesting.

Remember, if you can imagine it, you can program it.
