Instructor: So, as you learned over the last lectures,
you can run your node TypeScript code with just Node.js
if you are using a recent version of Node.js.
But Node.js isn't the only option you have.
Instead, there also are alternative run times,
alternatives to Node.js like Deno or Bun.
And these are simply alternatives you can install
on your system,
and then you can use them to run your Node.js code
with those run times instead of native Node.js,
if you wanna call it like this.
Now, these alternative runtime, Deno and Bun,
do not just support Node.js code
that you could also run with Node.js.
Instead, they typically also come
with extra features built-in,
and you can learn more about these runtimes
and what they offer
on their respective homepages and documentation pages.
But here, I at least wanna show you that with Bun installed,
so I did install Bun as described on that Bun homepage.
I can also run that app.ts file with Bun instead of Node.js.
And you see, that runs without any problems or warnings.
And that's simply an alternative to Node.js.
And I just wanna highlight here that both Deno
and Bun have that built-in TypeScript support.
And unlike Node, it's also not that strip only support,
but instead, they do support all TypeScript features.
So, that's just also something to keep in mind.
You have these alternatives if you're interested in them.
