React code create dynamic menu navigation

Abhijeet Jadhav — Thu, 12 Jan 2023 05:10:15 +0000

Here is an example of how you might use React to create a dynamic navigation menu:

First, you would need to create a component that represents the menu. You might call this component "NavMenu". Inside the component, you would define the structure and styling for the menu, as well as the logic for rendering the different menu items.

import React from 'react';

const NavMenu = ({ menuItems }) => {
  return (
    <nav>
      <ul>
        {menuItems.map((item) => (
          <li key={item.id}>
            <a href={item.link}>{item.label}</a>
          </li>
        ))}
      </ul>
    </nav>
  );
};

export default NavMenu;

In this example, the menuItems prop is passed to the component and it expects an array of menu items. Each item should have an "id" , "label" and "link" properties. These properties will be used to generate the structure of the menu.

Now you can use this component in other parts of your application and pass the menuItems prop with the desired data for rendering.

import NavMenu from './NavMenu';

const menuItems = [
  { id: 1, label: 'Home', link: '/' },
  { id: 2, label: 'About', link: '/about' },
  { id: 3, label: 'Contact', link: '/contact' },
];

const App = () => {
  return (
    <div>
      <NavMenu menuItems={menuItems} />
    </div>
  );
};

This is a basic example, in a real-world application, you might want to add more features such as active state handling, sub-menus, and more, but this example should give you a good starting point for building a dynamic navigation menu with React.

Use of child process core node js package to handle asynchronous code execution.

Abhijeet Jadhav — Thu, 20 Feb 2020 04:10:02 +0000

This sample example of the use of the child process to handle the asynchronous code of node js. We all know we used promises and async-await javascript primitive method to handle the asynchronous code execution but I have found another way to handle asynchronous code without using promises. If you go through child.js I have used two functions to take some time to execution but we want two functions to process data for next synchronous process execution so I have used the fork process for execution in the background and wait for message event observer to get process execution data.

File: parent.js

File: child.js

I am trying to find out the logic if without using promises and async-await javascript primitive method can we execution synchronous. Kindly if any another example above scenarios.

Handle async operations in parallel in Nodejs

Abhijeet Jadhav — Mon, 17 Feb 2020 04:18:35 +0000

This is the best example to handle async operations parallel in Nodejs. In this example, we have used the promises primitive datatype of javascript to parallel call while async operation. If you execute this script then output come after 3 seconds.

if check-in script apifirst take 2 seconds in execution and apiSecond take 3 seconds if you use the computer language like synchronized operation process to execute then it takes 2 + 3 = 5 seconds to execute output but in the case of NodeJs it only takes 3 seconds.
