jQuery vs. React?
When it comes to choosing between jQuery and React, it depends on your needs and preferences.
Why Migrate From jQuery to React?
There are several reasons why you might want to migrate your app from jQuery to React.
First, you need tocreate a React applicationusing create-react-app.
After you have installed these dependencies, you’re gonna wanna create a file calledindex.jsin yoursrcdirectory.
This file will be the entry point for your React software.
Finally, you’re able to move on to individual parts of your codebase and update them accordingly.
Handling Events
In jQuery, you could attach events to elements.
For example, if you have a button, you might attach a click event to it.
When someone clicks the button, the event handler will run.
React handles events differently.
Instead of attaching events to elements, you define them in components.
When somebody clicks the button, this method will run.
Each method has its pros and cons.
In jQuery, events are easy to attach and remove.
However, it can be difficult to keep track of them if you have a lot of events.
In React, you define events in components, which can make them easier to keep track of.
But they arent as easy to attach and remove.
For each event that you want to handle, you will need to define a method in the component.
This method will run when the event triggers.
React hasdifferent types of hooksthat you might use in your app, of which useState is one.
When a user clicks the button, the isShown state variable updates and the element displays only when appropriate.
In jQuery, effects are easy to use, and they work well.
However, they can be difficult to manage if you have a lot of them.
However, it can be difficult to handle errors.
In React, the fetch() method is more verbose, but it is easier to handle errors.
CSS
In jQuery, you’re free to specify CSS by page.
One way is to use inline styles.
It really depends on your requirements.
In general, inline styles are easier to use for small projects.
For larger projects, global styles are a better option.
you might deploy React on any static web server.
you’re free to also host your React app for free on GitHub pages.
