Hey everyone,

As a React developer, I wanted to share a tip on how you can improve the performance of your React applications using React.lazy.

React.lazy is a code-splitting technique that allows you to load code on demand, which means that your app will only load the code that is needed at the time. This can significantly improve the performance of your app, especially if it has a lot of components and large amounts of code.

To use React.lazy, you simply need to pass a function that calls a dynamic import to the React.lazy function. This will allow you to split your code into smaller chunks that can be loaded on demand as needed.

But here's the catch: since the component may not be immediately available, you need to render it inside of a "Suspense" component. The "Suspense" component allows you to show a fallback UI while the component is being loaded.

With this simple code, you can improve the performance of your React app and create a better user experience. I hope this tip helps you in your next project. If you have any questions or comments, feel free to leave them below!

I saw this online and decided to share, and I am looking to invest some hours in them here is a good Github Guide

Don't have to study all…you can learn the ones that are applicable to what you are doing as a dev

Weighing in on the matter,
Learning CMS is good and profitable. Knowing how to create themes and plug-ins is great.
But someone with React and Node skills(for example) can build anything besides shopping app or e-commerce sites. He is very valuable as compared to the one with only CMS skills. This is because he can make custom web apps. He can easily extend the functionality and add things that make your site stand out.
He can implement various algorithms and libraries to make sites very much optimized and efficient, since he's more technically grounded than his CMS counterpart.

Talking about the learning curve, CMS may take you lesser time than the learning React and Node or any other framework and language, but that's only normal since you will be more versatile with React skills than CMS skills.

Learning React or any other framework or language will make you more valuable as you can work in different companies.
If you check job openings, you will more than likely see jobs for these languages and framework as compared to WordPress. Even web development companies hire React/Angular/Vue developers because they make sites that are tailored to the customer's needs. This is because most small sites look alike since they are built with WordPress.

Again, take nothing away from CMS. If you want to learn it, go ahead.
But if you want to be extensible as a developer, you should learn languages and frameworks.

Peace.

If you don't want to wear it, give it to another person…

JavaScript is a scripting language used to make webpages interactive.
It has different datatypes which include arrays.
Arrays are used to store data of any type; i.e they can store numbers, booleans, strings, objects and another array in the same array.

When you are programming, you will often need to check if an array is empty or not.

Here's the way of checking if an array is empty using the

length

property.

Nice write-up.
But prospective web designers should know that learning web design will take you more than a month [color=#000000][/color] especially if you are gonna learn HTML, CSS and JavaScript.
but all in all, it's a great skill to master and I am willing to help anyone that wants to learn FREE
