I have the following instruction in a JavaScript of mine. The script works perfectly in any browser.

var prevItem = new Array(nsel).fill(null);

where nsel is an integer greater than zero.
However if I run it in Prince I get the following error on that line of code:

TypeError: value is not an object.

Any idea why? I have the same error even if I write:

var prevItem = new Array(nsel);
prevItem.fill(null); 

Prince does not yet support the Array fill method.

We have added support for the Array fill method to the latest build, thanks for letting us know!

Wow... good job. Thank you.
