Echo JS 0.11.0

Should be highlighted this is appears to be a commercial product, coming in at $700.

I'm happy to see that the JS for the spreadsheet demo (including jquery) is under 1mb... though I still consider 750k to be huge for a JS, for the functionality it isn't bad...  Didn't look at the other demos, or interact, was just curious as to the size.

This is not something you would probably want for most public facing sites/applications, one of the larger demos weighed in at 1.7mb of js... again, very impressive for the functionality.  I only hope that I can remember about these guys should I ever need this type of functionality again.

All of this has been available in extjs for years

A lot of it, yes... but I think the interface is a bit cleaner, and extjs is cumbersome to work with imho.  I don't have any use for this, and haven't for a long while, so can't comment.  I have written a lot of extjs code in the past, and would rather not look back at it.

All in one component.  fast.

Spread.Views (available as a Community Technology Preview) is data layout and presentation component for JavaScript developers. Quickly create grid, calendar, trellis, masonry, card, news feed, and timeline views from data. Tons of demos online and free download available.
