This is sadly a huge drawback and inconvenience. It doesn't even give you line level error reporting.

If you make a mistake in JavaScript you're kind of on your own figuring out where the typo or code error lies.

There basically isn't any debugging functionality.

These files contain both the compiled binary (the stuff used by the device)and your source code (the stuff you typed in or assembled as blocks).

It's worth exporting your code as downloaded files periodically and saving them as backups.

If you switch computers or user accounts on the same computer, your code won't follow you.

If you empty the browser cache your code will vanish like the morning dew.

(though Bluetooth transfer solutions do exist for some devices)

It's also not possible to transfer your code from most mobile devices over USB. It is possible to use a browser on a tablet or phone, but the site isn't optimized for mobile devices and is frankly awkward to use this way. The system also expects that you'll be coding on a personal computer.(Once the code is copied to your microcontroller, of course, it’ll work there indefinitely) It expects your computer is connected to the Internet. This system is not designed to be used offline.Microcontrollers have the same problems of bulk and power drain as 555 timer circuits, but offer vastly more sophisticated timing options! I'd either use totally simple self-blinking LEDs, or else go for a full-on automated solution, using a microcontroller (see below). And they're just not terribly flexible compared to what computers can do these days.

The circuits add extra size and expense, and also draw current themselves, which costs battery life if you have a portable model. Or unless you want to learn more about the fundamentals of analogue electronics. Personally, I'd avoid these traditional solutions unless you have a very simple special purpose application, such as the alternating lights on a railway crossing gate. Since the 1970s many blinky circuits have used now-venerable 555 integrated circuit timer chips. Early designs used relays, or a pair of transistors pointing back to back. People have been designing simple electronic circuits to make LEDs blink for as long as there have been commercial LEDs. There are thus many ways of automating light sequences that benefit a model maker. Since LEDs are easy to turn on and off – they don't require any strange power sources or anything – it's easy to make an electronic device that can control a group of LEDs in a sequence, or on a timer, or whatever you want. 19 Neopixels and educational microcontrollers.18 Neopixels (WorldSemi addressable "smart" LEDs).17 Drawbacks of educational microcontrollers.12 The Circuit Playground Express hardware.10 An animated light example for the Circuit Playground Express (CPX).5 Microcontrollers – the ideal solution.
