Advantages of using `Map` over `Object` when working with key-value entries in #JavaScript Any Key Type: Use objects/functions as keys. Preserved Order: Maintain insertion order. Performance: Efficient for frequent additions/removals. #js #tips #frontenddeveloper #dailytips #map #object

💡React Tip💡 Don't use useEffect hook unnecessarily when you can derive the value once the state changes. In the first code, we're using useEffect hook to calculate the total price once the quantity changes. Instead, we can do this calculation directly during render, which also avoids the need of using extra state for storing the total price, as shown in the second code.

In React, inline Styles are a way to apply CSS styles directly to a specific element using the style attribute. However, unlike traditional HTML, Where you use a string to define styles, in React you define styles as a JavaScript object. #react #inlinestyles #js #html

Let's talk about the #Singleton #Design #Pattern in JavaScript. The Singleton Design Pattern tells us that we can create only one instance, which we can use globally. You might have thought, "I've never used this Singleton design in my projects." But what if I told you that you're using it? Let me tell you where: If you are using "Redux," it means you are using the Singleton Pattern. Or If you are using "React Context," it also follows the Singleton Pattern. We have many examples like this. Here, I have written a small example in JS. #js #desingpattern #react

When elements are re-rendered, React uses the key to identify which elements have changed, added, or removed. This allows React to update the DOM efficiently, improving the performance of the application. #react #js #javascript

This React application generates passwords based on user preferences for length and character types (upper case, lower case, numbers, symbols). It employs state management with useState, constructs passwords randomly, and provides a user-friendly interface with options to copy generated passwords. Styling is implemented using Tailwind CSS utility classes. #react #js #webdeveloper #jsdeveloper #Javascript
