​​When choosing a programming language for Backend development, your choice determines how the product will operate, scale, and fulfill user demands. One of the most common dilemmas is Node.js vs Python. The two options are hugely popular and have their pros and cons. We work with both and are here to compare their advantages and disadvantages and help you to decide which one is better for your project. Decision Making Steps Choosing a backend development language, define your expectations first. Focus on the following points: . Is it a data-heavy app or an interface-focused program? Is its functionality mainly static or interactive? At this stage, analyze your competitors, market, and final user’s demand. Define the product kind It is essential to understand where your product will be used: in a specific region, nationwide, or internationally. The bigger the area, the more carefully you have to think about architectural and tech solutions. Define the area. It is vital to be unique and continuously demanded. It means thorough marketing research, understanding your main competitors, and having clear buyer personas. Conduct marketing research. The moment to understand how many available specialists with relevant experience you have and if you need to hire outsourcing developers. Analyze your resources. There are no perfect backend development tools. Analyze speed, security, interactivity, responsiveness, and pick which of those are on the highest priority. Clarify the main performance criteria. Python Python is an object-oriented, dynamic language appreciated for its simple syntax and universality. Python remains one of the most requested languages on the market. One of its main advantages is the support of multiple programming styles, making it well-suited for complex computational projects and simple websites. defines Python as the most popular programming language in 2020. It is used by 29% of developers worldwide. According to , 87% of developers who know Python use it as their main programming language. 27% of them use Python in web development, 28% – in machine learning, and 18% – in data analysis. Statista JetBrains’ research Python gives access to the Berkeley sockets API. This is the module that handles the client-server network. Python offers a simple and coherent API that corresponds to C’s equivalents of these system calls. Python has classes that make utilizing these low-level socket methods easier as part of its code. Pros Of Python Fast Development And Deployment Dynamic and object-oriented syntax allow Python developers to spend less time working on complicated code. Numerous packages, add-ons, and libraries provide ready-to-go options from the simplest web backends to complex scientific computations. These things make Python a perfect decision for the development of MVP and prototypes. As a result, companies can go to market faster, there is simultaneous support for various iterations, and a high percentage of reused code. Simple Syntax Python uses fewer code lines than other languages and development frameworks. It is not just about the volume, but it makes it easier to understand the code while working in a team. Python allows programmers to express complex ideas in a few lines of code. Python has the particular benefit of frequently using English terms rather than mathematical expressions. The code is easy to read and understand. Large Ecosystem Python responds to multiple development challenges. Even though the ecosystem is not new, a constant adding of new packages and add-ons keeps it relevant. For now, it is one of the best-suited languages for AI, computer vision, machine learning, data science, statistics, and other fields. Significant Community Python has been around for a while, so it built a big community around itself. Developers use open-source resources and tutorials, which makes professional growth and experience exchange easier. The community might seem unimportant at first, but it keeps developers involved and updated. Cons Of Python Speed Python will not be the best choice if you have high speed as a priority. Python easily handles intensive operations, but it takes more time compared to other languages. If you need to run multiple requests Node.js will suit you better with its asynchronous input and output. Mobile Versions Performance Low performance in mobile apps is a major issue. If the backend is slow by design, the user experience takes a hit. Another problem with adapting Python code to mobile is that it does not work well with native components. If you add on the after-effects from a not-so-compatible codebase with low performance, you will have a performance problem. Node.js Node.js is a runtime environment for backend development based on the JavaScript programming language. Node.js uses asynchronous, event-driven input-output. It indicates that the runtime environment may handle several requests at the same time without having to wait for the previous one to complete. Node.js is the most used programming framework, according to . About 53% of all developers use Node.js for their projects. Twitter, Aliexpress, Coursera, and lots of other giants created with Node.js. Netflix and Paypal chose Node.js to empower their microservices. It allowed them to shorten the startup time from 40 minutes to just 1 minute. Statista Node.js is a programming language that allows you to create WebSocket (a protocol that allows for a real-time two-way client-server network). In online applications, WebSockets are an alternative to HTTP communication. The channel is maintained open once the connection is formed, allowing for a highly fast connection with little latency and overhead for the client-server network. Chats, online multiplayer games, Google Docs, and other common use cases are just a few examples. The main advantage of Node.js is how it handles complex concurrent processes. Large companies choose it to power their infrastructures because of its proven capacity to handle large workloads quickly. Pros Of Node.js Fast Performance The main reason to go for Node.js is its fast performance. It handles numerous requests in parallel on a single Node.js server. Node.js uses the Google Chrome V8 engine as a runtime environment to execute JavaScript. The engine uses just-in-time compilation to process JavaScript code and provide instant output quickly. It makes Node.js a go-to option for interactive development. Thanks to this, you get a great user experience, making Node.js a top choice for real-time apps, messengers, gaming apps, etc. Full Stack Web Development Full-stack web development is a trend – enterprises like Medium, Airbnb, Paypal, Netflix switched to Node.js to use JavaScript both on the frontend and the backend development. It assures: Working with a single stack means that you may work with a smaller team of full-stack developers instead of frontend and backend ones. Better teamwork. Developers are free to reuse fragments of code from frontend to backend development and vice versa. It reduces the number of code lines, impacts delivery speed, makes refactoring and maintenance simpler. Code reuse. One of the most widely used programming languages is JavaScript. A skilled front-end engineer can easily learn Node.js since the basic principles are the same. So it is easier to become a Full-stack web developer. A large pool of talents. Reusing JavaScript across the entire development process on the Node.js server speeds up the delivery and makes communication easier. It is a huge advantage when all team members can understand the code. Microservice Development Node.js server has many NPM packages. Netflix and Paypal made a simultaneous migration to Node.js and microservices, which gave amazing results. They got rid of code duplication, organized the architecture, introduced additional functionality, and improved user experience. Cons of Node.js Low Performance With Big Data At larger volumes, Node.js is not well equipped to handle complex operations. Its advantage is the quick processing of multiple simple requests, but anything complicated leads to delays. . When talking about fast I/O operations, the tasks are over quickly. But if it is a computation, it takes a while to get the result. The thread comes up blocked, and other operations cannot go through. A single thread event loop JavaScript is a front-end language that adds to Node.js' limited CPU capabilities. It does not communicate as smoothly with the hardware and processing units. Node.js and JavaScript. Suppose your app has to run complicated operations. Node.js is not a good choice. There are ways to make Node.js perform better with complex tasks, but the default functionality is not well-equipped. Messy Syntax The programming language is built on NPM modules, which allow you to extend the built-in functionality and create almost anything. However, a specific module can perform well on its own but be incompatible with the rest of the system. Some NPM modules may be incompatible and need to be reset. If you run big infrastructure, errors can lead to crashing. Python Use Cases : working with data gathering and analysis. Apache Spark, Facebook data analysis systems, and voice recognition systems use Python as their primary programming language. Data science : making calculations, processing a lot of data, and providing analytics. Complex web platforms : Python APIs like Scribus, Maya, and Blender are great for creating animation and complex graphics. 2D and 3D GUI : FreeCAD, an application for 3D modeling, analytical software like Abaqus, and others are built on Python. Scientific software : collecting data for forecasts and analytics and displays the result in intuitive dashboards. Scrapers and parsing software : writing automated testing development frameworks. Testing and development Node.js Use Cases : creating an uninterrupted streaming environment. Streaming apps : when several users are audio- or video conferencing or editing a file simultaneously, Node.js assures real-time updates. Trello is a brilliant example. Collaboration platforms : multiple APIs and NPMs allow creating two-side exchanges via a single connection, which is what chat development is based on. It also has add-ons for notifications and real-time server-side updates. Real-time messengers Conclusion Node.js and Python stacks are excellent backends that offer impressive possibilities to developers. Python is great at executing complex operations and supporting innovations, but it loses in speed. Node.js has outstanding performance but is not good at handling complex operations. The final decision should depend on the project type. First posted on https://incorainc.com/node-js-vs-python-what-are-the-pros-cons-and-use-cases/
