Learn Node.JS with Free Lessons & Tips

The ease of learning Node.js or PHP depends on various factors, including your previous programming experience, familiarity with certain concepts, and the specific requirements of your projects. However, here are some considerations:If you're already familiar with JavaScript, learning Node.js may be easier for you since it leverages your existing knowledge. Node.js uses JavaScript for both server-side and client-side programming, allowing you to reuse your skills across the full stack.Both Node.js and PHP have large and active communities, as well as extensive documentation and resources available online. The availability of tutorials, guides, and community support can significantly impact the ease of learning for both technologies.

 Node.js itself is secure, but the security depends on how you use it. Regularly updating dependencies and following best practices are key to maintaining security. Is Node.js visible in the browser like JavaScript? No, Node.js runs on the server-side, not in the browser. JavaScript running in the browser can interact with Node.js via APIs, but Node.js code itself isn't visible or accessible from the browser.

I would be surprised if it was ousted. Consider the following advantages

Since NodeJS uses JavaScript developers need to learn a single scripting for the client and server side (currently you will need to know JavaScript and one of the server side scripts like PHP, PERL, Python or Ruby)
NodeJs has a large repository of applications that power almost every conceivable use case in the industry
Projects rely on NodeJS for Automated Testing and Continuous Integration e.g Grunt: The JavaScript Task Runner, gulp.js, The web's scaffolding tool for modern webapps etc.

While Node.js provides the runtime environment for server-side JavaScript execution, it's relatively low-level when it comes to building web applications. Express.js provides a higher-level abstraction that simplifies server-side development by offering features like routing, middleware, and templating engines.Express.js makes it easy to define routes for handling HTTP requests. You can define routes for different HTTP methods (GET, POST, PUT, DELETE) and URL patterns, making it straightforward to create RESTful APIs or handle various types of requests.
