Let's discuss your "JavaScript Calculator"

project link - http://codepen.io/mikeale03/full/dXJdaN/. trying to replicate my windows 7 built-in calculator.

Ha, that’s funny, I was replicating my windows 7 built in calculator, too. Looks like our calculators are quite similar. Here’s mine: https://beekey.github.io/calculator/

Thank you, @mikeale03 :slight_smile: I put a lot of effort into that calculator. Yours is just as good, as I said, they look quite a bit alike.

I went for the oldskool look in terms of functionality, buttons and the LCD screen. Have a play, any unexpected behaviour please let me know!

Here’s my JavaScript Calculator: http://codepen.io/adamgibs/full/QERqpN/. Pretty bare bones but it gets the job done.

Here is my calculator! I use Angular Material for it. Feedback is welcome, especially about my Angular code. Thanks!

Great to see so many people have made it this deep into FCC!

Here’s my calculator, can’t wait to take a look at what some other people have done.

Hi, Santakmishra, took at look at your calculator, and the basic functions seem to work, but there’s no log per the the project. Am I missing something?

RickStewart: Great project! Impressive stuff.

Hi Superking,

I tried your calculator, and I love the idea of using keyboard input, but it doesn’t seem to work, at least not in Chrome.

Also, no log!

Mizu, good stuff! I like it. I tried a bunch of long chains of operations and I always seemed to get the correct answer. I like the way you built the log into the main display, too. That was a nice solution.

A very old calculator

I was in a class of electronic circuit design when the instructor got this thing out of his pocket. It was a little bigger than a pack of king-sized cigarettes. He switched it on and blinking red numbers started to appear. We all dropped our sliding rules and our jaw. Of course, we, poor students, couldn’t afford this $500 gadget.

Well, it is somewhat clunky, but it works… somewhat.

Here’s my one!

I learned so many things coding this one. Can’t wait to get started on the Pomodoro!

That’s awesome :smiley: The digits on the screen are a bit difficult to see though, perhaps you could make the red in the background a tiny bit dimmer?

Great CSS on this one. The calculator has been my favorite FCC project so far, maybe because it’s a “real” app, even if it’s one that’s been done plenty of times before.
