Cannot create a Uint8ClampedArray

Using the web IDE, I try to load just this one line:

var typedArray = new Uint8ClampedArray([1, 2, 3, 4]);

... and get this error:

Uncaught Error: Constructor should be a function, but is undefined
 at line 1 col 22

What am I missing?

Do you have up to date firmware installed?

And which board are you using? Some of the non-Espruino boards have some things removed in order to fit Espruino into their smaller flash memory sizes.

I did not have up-to-date firmware; thanks for mentioning that. After upgrading it, I found the memory usage to be much better with arrays! Looks like it was some optimizations you did last year.

Great! Yes, I've been able to optimise it a bit in the last year or so. There'll be some more big improvements coming in 1v82 as well!
