Qu’est-ce qui distingue les langages de programmation front-end et back-end ?

Front-end: 📍Deals with user interface (UI). 📍Utilizes languages like HTML, CSS, JavaScript. 📍Executes in browsers. 📍Focuses on client-side operations. 📍Shapes user interaction and visual elements. Back-end: 📍Manages server-side operations. 📍Employs languages like Python, Ruby, Java. 📍Handles databases, server logic. 📍Executes server requests, data processing. 📍Secures data, manages application functionality.

Front-end languages like HTML, CSS, and JavaScript (or Typescript) shape what users see and interact with in their browsers, while back-end languages such as Node.js, Java, or python handle behind-the-scenes tasks like managing data, logic, and server operations. Together, they work via HTTP requests to make websites functional and user-friendly.

Front-end Languages (e.g., HTML, CSS, JavaScript): Focus: User interface and experience. Responsibilities: Crafting the visual elements that users interact with directly. Examples: HTML structures content, CSS styles it, and JavaScript adds interactivity. Back-end Languages (e.g., Python, Java): Focus: Server-side operations and data management. Responsibilities: Handling databases, user authentication, and server tasks. Examples: Python for versatility, Java for scalability. In essence, front-end ensures a captivating user interface, while back-end manages the functionality behind the scenes. Both are integral for a seamless web experience! 💻✨ #Programming #WebDevelopment #TechExplained

Frontend: - Focus on user interface, user experience. I.E creating attractive, easy to use, accessible, and user friendly app. - keen about how data cached at client, which data to save in local storage/cache/session/cookies for fast performance and less loading time. - uses languages and libraries such as HTML, CSS, JS, React, Angular. Backend: -Focus on dealing with data and how to make it available to UI. - includes design, implement and test the APIs and databases. - keen about caching data at server side. - includes authentication and authorization of the user requesting data. - includes app architecture, I.E micro-services, Load balancing - uses Node Js, Express, Java, DotNet core, Restful APIs

Here are the top 5 most used backend tech used in production: - Node.js - Express (uses javascript) - MongoDB - Spring boot (uses Java) - SQL

The back end is the part behind the front end where the code runs the server part that does not appear on the computer screen. Programming languages include python, which is an interpreted language, and Javascript.

Em meus trabalhos em todos os casos que envolve um desenvolvimento que usa PHP, Python e etc. É sempre necessário um conhecimento da versão do servidor, acesso a instancia que executa a aplicação e tudo que isso envolve, tais como segurança e performance que deseja ser alcançada.

Node.js is a powerful runtime environment that allows developers to use JavaScript on the server side, making it a versatile choice for both front-end and back-end development as well. Node.js is good at handling lots of tasks at the same time, making it great for building websites that need to handle many users at once. It works well for real-time features, and developers often pair it with a framework called Express.js to make building the back-end part easier. Whether you're working on APIs, managing data, or dealing with server stuff, Node.js makes it easy to use JavaScript for the whole web development process.

Back-end Programming: Responsibility: Server management, database operations, application logic. Languages: Java, Python, Ruby, PHP, Node.js (JavaScript). In summary, the back-end manages server-side operations and data processing.

Imagine building a house. The frontend is like the design and decorations inside – how it looks and feels. It's what people see and interact with, like choosing colors and furniture. On the other hand, the backend is like the structure behind the walls – the plumbing and wiring. It handles things you don't see directly, like storing information and making sure everything works together. So, frontend is about making things pretty and easy to use, while backend is about making sure everything works smoothly behind the scenes.

We can make an analogy with a restaurant, the front-end would be the waiters, who would be in direct contact with the customers, to know what each customer wants, after the customers make their requests, the back-end would be the cooks who prepare the food that will be requested by customers, they would make it available. The front-end and back-end work in harmony to make the smooth functioning of an application possible.

>> Building a website is like hosting a party. TypeScript managed the front-end guest list, adding magic. Node.js in the back-end orchestrated seamlessly, creating a tech symphony that impressed everyone. >> Front-end languages are artists. TypeScript, the meticulous painter, ensures perfection. Back-end languages act like architects, balancing structure. It results in digital marvels—both visually stunning and robust. >> Software development, a blockbuster. Front-end languages, visual storytellers, with TypeScript as our grammar-savvy narrator. Back-end languages, scriptwriters, craft plot twists. Magic happens when both collaborate, weaving an epic software tale.

Existem varios padroes de projetos que são interessantes no mercado, mas o que mais me chama atenção é o padrão MVC, singleton e etc. Esses padroes fazem a distição clara das camadas de acesso do usuario e a camada de acesso da aplicação. Nesse padrão o Model é conhecido como um modelo de um objeto utilizado no meu negocio por exemplo USUARIO. View é uma camada de aplicação recebida pelo Control que é responsável pela camada de controle a aplicação, ele trata de requisições e recursos necessario na View vindos do Banco de Dados por exemplo ou um controle de acesso.

front-end: Manages user interface and interactions using HTML, CSS, and JavaScript. Sends requests to the back-end. Back-end: Handles server-side operations, processes requests, and interacts with databases. Sends responses, typically in JSON format, back to the front end. Interaction: Front-end and back-end communicate through requests and responses, allowing dynamic, data-driven updates on the user interface.

Contrary to popular opinion, it is relatively easy to get started with both front-end and back-end languages. However, building valuable, scalable applications often involves sophisticated front-end and back-end code. On the front-end side, user interface elements need to be sensibly and seamlessly organised for the user for easy adoption and user preference, whilst being performant on a diversity of device capabilities, screen sizes and usage methods. On the back-end side, operations dealing with huge amounts of data ought to be done as fast as possible. On both ends, code also needs to be well organised so that the project is easily maintainable and extensible. As such, both front-end and back-end have their relative learning curves.

Again, front-end isn't necessarily web. That said, some front-end languages can be quite challenging to master. I'd suggest looking at it from another angle: each "end" requires a different set of traits. It's up to the developer to know where they fit best.

The advantages are that the front end can produce interactive pages while pursuing design. It is a profession that combines designers and engineers. The cons are that the pages become more complex and difficult to produce. Recently, with the advent of mobile devices, tablets, and other responsive web devices, it is difficult to adjust the screen size, etc. The advantage of back-end engineering is that it uses Python, so it is possible to change careers from back-end engineer to artificial intelligence engineer. The disadvantage is that it is a modest job compared to the front end. It also requires multiple programming languages and framework skills. Knowledge of the server side is also required.

An advantage of JavaScript is that there is a huge variety of libraries to help with various recurring tasks in a simplified way, for example Javascript has libraries to: export .pdf, read CSV files, capture the screen, and much more. One of the disadvantages of Javascript is the enormous size of bundles and third-party libraries, which is often too complex to understand.

Como todas las herramientas, las que pueden utilizarse para muchas cosas, no son las mejores para funciones especificas. Una navaja suiza puede resolver muchos problemas, pero no debería ser la herramienta de un especialista.

Programming languages are used for different purposes. What type of system development is needed? For example, if you want agile development, it would be an interpreted language such as Python. However, if you want to do large scale development, it will be Java, C++, etc.

Not in order, first, consider the language's ecosystem. Simply put, this determines what you'll be able to build within the language without expending huge amounts of time and energy. For example, if you want to build a web application, JavaScript's and Python's ecosystems includes lots of libraries to help you get started, with lots of community questions answered. Whereas Julia? Not so much. Next, especially if you're new, consider the learning curve of the language. Some languages are designed to be easy to grasp (e.g. Python), and others are designed for other purposes (e.g. Rust). Ensure that you accept the learning curve before you start climbing. Finally, choose a language you can eventually feel comfortable writing code in!

The purpose of the project will be one of the determining factors in choosing the programming language, for example for e-commerce projects a language widely used in the back-end is PHP, however for a project with Machine Learning this may not be the best option , for this case Python would be the most suitable. Projects such as chat to exchange SMS, a good recommendation is Javascript (Node.js).

La tecnología a utilizar debiera ser la más económica y eficiente para cumplir la tarea. El alcance del requerimiento y las ofertas disponibles son parte de la eficiencia.

Picking the right language for system development is like choosing tools for a masterpiece. No one-size-fits-all answer exists; it's all about matching the language to the project's personality. Want a simple, static page? Front-end languages shine. For complex, dynamic apps, the dynamic duo of front-end and back-end is the go-to. The choice also dances with factors like purpose, functionality, and the audience of your digital creation. Think of it as tailoring a suit – the language should fit the occasion, ensuring compatibility with the chosen platform or device. It's a personalized journey through the coding landscape.

There are numerous resources available for learning both front-end and back-end development. Below you can find valuable content: 1. MDN Web Docs (Mozilla Developer Network) 2. freeCodeCamp 3. Udemy 4. Codecademy 5. Frontend Masters 6. Youtube

It really depends on your learning style and motivations. If you already have a project in mind, I suggest just starting. You can start by googling (or asking ChatGPT) what you need to build this or that. Eventually you'll get some answers, and for each thing you don't understand or know how to do, you can google (or chatGPT) what it is, or how to do it. This lands you in the right tutorials for exactly what you want. If you don't have something that you want, look for something you want to build, because it will be much more motivating seeing something you like come to life as you learn and climb over walls.

I recommend starting with any course for beginners like CS50 or short courses on LinkedIn. You can try to write code in several programming languages, and later you will already decide what to choose and the direction of your development.

I wouldn't rely on W3Schools as the best source of web content. MDN would be a better choice. The best learning strategy, for me, is getting your hands dirty. Pick whatever language or framework you're trying to learn and build a micro app with it. Don't stick to tutorials on blogs and YouTube, really put the effort to build something yourself, regardless of how simple it is.

I want to highlight that having diverse sources of knowledge is always the way to go. I recommend to the thousands of developers I have helped over the past 25 years that if you can have some books, read articles online and most importantly find a good community forum to ask questions in is a perfect setup. Many seasoned developers, like myself, often help for free on community forums like sitepoint.com and do so regularly. Experts also work together to deliver adequate answers and often feed off of one another to help users with example code and more. It is always worth your time to ask clear and concise (along with a little code you are working on) to a good forum.

Backend programming language is focus on about data manipulation with with database, and receiving and sending datas with front end user interface. Frontend programming languages is only focus on about GUI and sending and receiving datas with the backend languages with Api https.

Algunos lenguajes de programación son utilizados tanto en desarrollo front-end como en back-end. En desarrollo web es común por ejemplo tener interfaces de usuario diseñadas para comunicarse con el backend donde el usuario final son los mismos desarrolladores. Lo que no cambia al final es que el explorador o la aplicación en front-end sólo va a interpretar archivos HTML, CSS y JS.
