ReactJS: How to create a toggle show/hide in less than 30 seconds

ReactJS: how to create a toggle show/hide in less than 30 seconds | Noobie Programmer

Since I've been trying to compare vanilla javascript, jquery and reactjs on which is the easiest to use. I made a simple program on how to hide/show a simple div by clicking a button in each ways.

ReactJS vs Javascript vs JQuery

Here is the javascript:

Here is the jquery:

And, most especially using ReactJS:

Code

So since my favorite is react let's break down the code one by one. And then later on you'll realize it is so easy to create a toggle or use any condition with react.

Of course before anything else we need a react template where all the basic imports are already available to use. Since I'll be using codepen here's my template just in case you want to create a react pen: https://codepen.io/noobieprogrammer/pen/VwaRrJb

First we add a button:

And some text inside a div that we wanted to hide:

but nothing is happening right? so let's add a state variable  named show. What we want is to toggle it from true to false and vice versa everytime we click the button. So first let's initialize it to false in the constructor since we want the div to be hidden first once the page is loaded:

Then let's create a toggle method who will toggle the show variable everytime the function is called:

Let's pass it on the onClick property of the button. Also, let's change the text of the button so that it changes depending on the state of the show variable:

And one last thing is to add an if else condition on the div using the ternary operator. Show it if the show variable is true otherwise return null or basically nothing.

And we are done! and here's the final code:

Conclusion

As what you can see from the code above, it is easy to create a ReactJS toggle hide/show when compared to vanilla javascript. It's almost as easy as in JQuery.

The only problem with JQuery is it's hard to maintain when the code or logic becomes bigger and more complex.

But, with ReactJS we could easily store and update the state variables however we want to. It's fast, easy to read, and most importantly beginner friendly.
