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!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
