Calculator App

What I learned

I had to think a lot with this one, like how to prevent user from :

• typing more than one operator at a time ( e.g. 7++2)
• using multiple dots on a single number ( e.g. 3.00.5)
• typing a dot without a number before ( e.g. .3)

I also had an idea for the theme switcher : I'm putting all my DOM elements into an array, and interating through it with a forEach(), this way I'm using one line of code instead of one line for each DOM element I wish to change.

I made the toggle by myself this time, without getting any help or ressources on the internet, I'm pretty proud of it.

I used the .replace(/x/g, "*"); function, which replaces all the x by *, which makes it more readable for the user.

Way of improvement

It would be a nice addition to allow the user to type on his keyboard instead of clicking.
