JSX

Conditional rendering is an essential concept in React that allows you to dynamically output different components or sections of JSX based on certain conditions. This ability provides powerful flexibility when building React applications. In this article, we will explore two common methods of conditional rendering: the ternary operator and the logical AND operator. The Ternary Operator The ternary operator is widely used for conditional rendering in React. It is concise and straightforward, making it a popular choice among developers....

Introduction to JSX JSX is a technology introduced by React that allows developers to write declarative syntax for defining a component’s UI using JavaScript. It is not a mix of HTML and JavaScript, but rather a way to describe the UI elements using JavaScript. JSX offers many advantages when working with components in React. A JSX primer To define a JSX element, you simply write JavaScript code that resembles HTML syntax....

When working on a menu that displays a list of items, each with its own icon, you may come across the need to dynamically choose which component to render based on certain conditions. In this blog post, we’ll explore different approaches to achieve this in React. Hardcoding Components in the Menu Initially, you might hardcode the components directly in the menu array. For example: const menu = [ { title: 'Home', icon: <HomeIcon className="mr-3 ml-1 h-5 w-5" /> }, { title: 'Notifications', icon: <BellIcon className="mr-3 ml-1 h-5 w-5" /> }, { title: 'Profile', icon: <UserIcon className="mr-3 ml-1 h-5 w-5" /> } ]; This approach works well if the components remain the same throughout the application....

In React, when writing JSX, there is a limitation: you can only return one parent item. You cannot have multiple elements directly under the return statement. However, there are several solutions to overcome this limitation. Solution 1: Wrap Components and Elements in a <div> One common way to solve this issue is by wrapping the components and other HTML elements in a <div>: const Pets = () => { return ( <div> <Dog /> <Cat /> </div> ); }; However, this approach introduces an additional HTML element which may not be necessary in the final rendered HTML....

In this blog post, I will walk you through the process of moving a website from Hugo to Astro, a simpler solution that eliminates the need to work with Hugo templates when making changes. I find Astro to be a great choice for this migration because it allows me to use JSX, a syntax I am more comfortable with, and also gives me the flexibility to incorporate frameworks like Svelte or React in the future....
