How to write JavaScript in server side?
JavaScript can be used in server-side scripting by leveraging server-side frameworks such as Node.js. In Node.js, you can write JavaScript code and use the server-side features to manage file access, create and manipulate databases, and build web applications. Express.js is a popular server-side framework for Node.js that enables developers to create robust backend applications. It is a great tool for writing server-side logic in JavaScript. In addition to Node.js and Express.js, there are other server-side frameworks like Koa.js, Sails.js and Hapi.js that enable developers to write code in JavaScript. These frameworks provide APIs that can be used to access databases, handle requests, and manipulate data. They also provide helpful utilities, like template engines, which enable developers to create dynamic applications quickly. Overall, you can use JavaScript on the server side by leveraging server-side frameworks such as Node.js and Express.js. These frameworks provide powerful tools and APIs that can be used to build robust backend applications in JavaScript.

It provides developers with insight into Java application performance and assists with tuning applications and optimizing for performance. 2. Java Mission Control (JMC): This is an advanced profiling and diagnostics tool for Java applications. It is a powerful tool for troubleshooting Java performance and isolating application problems. 3. Java Virtual Machine Tools (JVMTI): This is a set of tools that provide the ability to instrument and monitor Java Applications by observing and manipulating the state of a running JVM. JVMTI can be used to detect memory leaks, potential threading issues and more. 4. VisualVM: This is a visual overview of the running applications and the active JVM processes. With VisualVM you can view memory utilization, network traffic and various other metrics. 5. JMX (Java Management Extensions): This provides the ability to connect to a running application and monitor it from an external application. JMX can be used to detect memory leaks, monitor the JVM, and view application performance metrics such as memory usage, CPU usage and thread counts.
