What does a javascript developer do?

JavaScript Developer in a nutshell: 1.Creates and maintains web apps, mobile apps, and more using JavaScript. 2.Builds interactive elements and user interfaces. Sometimes handles server-side logic (Node.js). 3.Writes clean, efficient, and maintainable code. 4.Needs to know JavaScript, HTML, CSS, frameworks React,Angular Vue js .....

In this cosmos of “World Wide Web”, JavaScript developers are the real spiders responsible for building and maintaining the best ideas, user experience and along with works on the optimisation to reduce cost and enhance performance. The business mainly depends on how user experiences on the particular website with limited search query resulting best results. JS developers have to imagine scenarios as a developer and sometimes user too.

JavaScript developers are magicians of the web, creating interactive experiences from nothing. They transform static web pages into dynamic and engaging ones. A fun fact: JavaScript was born in only 10 days, and now it runs the interactive web!

In my view, a JavaScript developer is a vital contributor to the world of web development, specializing in harnessing the power of JavaScript to breathe life into web applications. Primarily focused on front-end development, these professionals work intricately with HTML and CSS to create dynamic and engaging user interfaces. Proficiency in popular front-end frameworks like React, Angular, or Vue.js is often a cornerstone, enabling the development of sophisticated and responsive features. The role extends beyond the front end, as JavaScript developers adeptly navigate the back end using technologies like Node.js. This involves managing server-side logic, databases, and handling server requests.

A JavaScript developer creates interactive and dynamic elements on websites or web applications. They use JavaScript, along with frameworks like React or Angular, to enhance user interfaces, add interactivity, and ensure smooth functionality.

JavaScript is similar to picking up chess. You can get the basics (syntax) in a few hours, but it takes years to perfect. A piece of advice from my journey: don't just learn to code, learn to think like a coder. It's not about remembering syntax, but about finding solutions and thinking rationally.

Dominio de JavaScript y comprensión de sus conceptos fundamentales como el DOM, JSON y AJAX. Experiencia con frameworks y bibliotecas populares de JavaScript, como React, Angular o Vue.js.

Stay updated with the latest trends, features, and best practices in the JavaScript ecosystem. Embrace collaboration, seek help when needed, and have fun exploring creative solutions with JavaScript.

The number one tip for a JavaScript developer is to either use JSDoc or TypeScript for type annotation. It becomes too hard to manage the project in the future if not so. Also don't use a third-party npm package for every problem.

1. Write modular and reusable code to facilitate easier maintenance and future enhancements. 2. Follow coding standards and conventions to ensure consistency and readability across the codebase. 3. Use version control systems like Git to track changes and collaborate effectively with other developers. 4. Embrace test-driven development (TDD) or behavior-driven development (BDD) practices to write more robust and reliable code. 5. Continuously invest in learning and skill development by exploring new JavaScript features, tools, and frameworks

Effective communication is key. Documenting code, participating in code reviews, and providing constructive feedback on LinkedIn have been vital. Additionally, embracing a test-driven development (TDD) approach has improved code reliability. Constantly seeking feedback from the community, whether on GitHub or LinkedIn, has helped me refine my coding practices.

Git is really useful for its ability to manage code changes effectively. You can track every modification, which is great for keeping things organized, especially when fixing bugs or adding features. When working with others, Git lets everyone work on different parts simultaneously, and then blends those changes smoothly. It's fast and adaptable, fitting into various workflows with ease. Essentially, Git provides a reliable way to manage your code, making collaborative projects much more manageable.

1. Online platforms like Udemy, Coursera, and Pluralsight offer a wide range of JavaScript courses catering to beginners and experienced developers alike. 2. Explore free resources such as Mozilla Developer Network (MDN) and JavaScript.info for comprehensive documentation and tutorials. 3. Books like "JavaScript: The Good Parts" by Douglas Crockford and "JavaScript: The Definitive Guide" by David Flanagan provide in-depth insights into JavaScript concepts and best practices. 4. Engage with the JavaScript community through forums, meetups, and conferences to network with peers and stay updated with industry trends. 5.Consider enrolling in bootcamps.

Learning JavaScript is a long journey you can never be an expert by taking one or 2 courses. But starting is all one needs, w3 school is a good site for beginners and for advanced javascript BootCamp courses are outstanding to learn with code challenges, and Udemy courses are quite reasonable to buy and worth the money.

In my experience, you shouldn't marry a particular course or resource. Use all the resources you have. There are plenty of incredible free resources. Use one resource as your main roadmap, but if you stumbled upon a concept you don't understand much, feel free to search for other resources for that particular concept. I've found javascript.info to also be a really good source to learn JavaScript.

FreeCodeCamp is the number one place. It's free and has a lot of quality content. If you can pay a bit I also recommend Frontend Masters. It's a bit expensive but it's the best and most quality resource out there to learn JavaScript technologies.

For learning JavaScript, platforms like Codecademy and freeCodeCamp offer interactive courses and practice platforms like Codewars provide in-depth knowledge and coding challenges.

To enhance your JavaScript skills through practical applications, consider building projects like a dynamic web portfolio using HTML, CSS, and JavaScript to showcase your work. Create a weather app that fetches data from a public API and displays real-time weather information. Develop a task manager with features like adding, updating, and deleting tasks using a front-end framework like React. Engage in open-source contributions on platforms like GitHub to collaborate with the community and gain exposure to diverse coding styles. These projects provide hands-on experience, demonstrate problem-solving abilities, and contribute to a robust portfolio.

Here is the list of projects for you to get started with web development: - C# compiler (Compiles C# code into JS) - Vacuum cleaner (cleans shitty web pages) - NodeJS cleaner (kills unused node instances) - Telegram captcha - (ask humans to prove that they're human using 2FA) Once you build these, you can start applying for Jr. Frontend Dev jobs :)

You can try some of the below mini projects to master Javascript: 1. Weather App: Integrate with Google Maps to provide weather data based on user-selected locations. 2. Delivery App: Create a delivery application akin to Dunzo or Swiggy Genie. 3. Live Streaming App: Implement live streaming and video conferencing using WebRTC. 4.

Contribute to open-source projects on GitHub, showcasing your skills and collaborative spirit. Create a personal website or blog, highlighting your experience, skills, and projects, and sharing your knowledge with the development community.

a few more considerations for JS developers: Keep in mind that different browsers may interpret JavaScript code differently. Test your code on multiple browsers to ensure compatibility and provide a consistent experience for all users. Keep in mind that different browsers may interpret JavaScript code differently. Test your code on multiple browsers to ensure compatibility and provide a consistent experience for all users. Monitor the performance of your JavaScript code and optimize where needed. Use performance profiling tools to identify bottlenecks and optimize critical code paths for better user experience and faster page load times.

Javascript language is used now both for Front End , Back End and Automation too. As a Javascript developer staying on top of proposals or features that gets added to Javascript language is necessary. Prefer Feature checks rather than browser checks. One noticeable pattern is Typescript adoption by Javascript developers in building enterprise web applications. Which pushes Javascript developers to be aware of Typescript happenings too. As a Javascript developers, be more open to adopt any new Frameworks and Libraries. Always stay curious in understanding the internals of these Frameworks and Libraries and use them wisely.

Continuous learning is essential for a JavaScript developer. The JavaScript landscape evolves rapidly, so commit to continuous learning and skill development. Stay curious and explore new libraries and frameworks to expand your skill set. Remember to prioritize understanding core concepts deeply rather than chasing after every new trend.
