Deno: Getting build errors

[mwoodpatrick]

I'm getting the following build errors when builing

https://github.com/second-state/ssvm-deno-starter

I don't see the definitions for these missing functions, where are they defined

The CLI errors seem to indicate you're not running/building with the --unstable flag.
Can you try again with that flag?

Yep, just realized that was the issue, paper that went with this repository:

https://www.infoq.com/articles/deno-loves-webassembly/

Did not list those flags see:

https://github.com/second-state/ssvm-deno-starter/issues/1

for details, close that issue, closing this one, many thanks for the very prompt and accurate assistance, much appreciated

There is an update to the article here. I will see if InfoQ can update their web site. Thanks!
