Once you've uploaded code, you can inspect and change variables (including functions!) while your program is running.
I was amazed at how difficult it was to get started with (and then to debug) most Microcontrollers (especially ARMs), and the lack of support for different platforms. I thought that by putting the development tools on the device itself I could come up with a microcontroller board that could be programmed easily from almost any kind of computer.
Not only that, but your source code is on the board itself. If you make something with an Espruino board and need to change it a year later, your original code is still there waiting for you!
Note: while prices are in USD, Puck.js devices are shipped from England. If you live in the UK or Europe, VAT is included in the price you pay. If not, you may be liable to pay your country's import tax when you receive the package.
