Programming editor in your pocket.

JavaScript Anywhere is one of the oldest development environment on iOS since 2010.
It's a simple and portable editing tool for web engineers and designers.

- Write JavaScript, HTML and CSS source code.
- Preview on internal browser.
- Show console logs or errors.
- Import project / Download images form web.
- Send e-mail / iTunes file sharing to export.
- Configure editor styles.
- Simple server for Wi-Fi
- Export to / Import from Dropbox.
- Project templates (Basic/jQuery/React/Bootstrap/p5)

That's all. JSAnywhere is minimal forever.
Happy coding!

Decent start

It does the most basic, which is editing HTML/CSS/JS, but of course it is so basic that you need to be very careful in typing and also there is no help. Going to that next level is really a full-ide and a completely different project.

In the meantime I would suggest you sort out the refresh bug mentioned earlier. You cannot change the CSS/JS without either updating the HTML twice as Neal mentioned or else killing the app and restarting.

If you can allow us to select different fonts that would be useful too.

Please add Syntax Highlighting

I like the app, but I really miss syntax highlighting.
It contains ads but they're refreshingly unobtrusive. Still I'd like the option to purchase a pro version with no ads whatsoever.
An ad-free version with Syntax highlighting would receive 5 stars from me.

This app is the best JavaScript app I found. Simple programs work very with it, but unfortunately as soon as I start doing more complex programs (mainly requiring inputs for a variable) it doesn't ask (prompt) for the input. I have had to make do with using the 'confirm' command to display data, as using 'print' or other commands of that like are not valid commands in this app. The app is good for more experienced programmers, but not for beginners looking to learn. I hope in future updates you might fix some of the stated problems (it hasn't been updated for 8 months) but until then it proves almost worthless to me.
