Check out this example code I saw:
import * as React from 'react';
const Count: React.FunctionComponent<
count: number; // this is the line that confuses me
> = (props) =>
return <h1>props.count</h1>;
;
export default Count;
That object structure is defining expected props, but since when is it syntactically correct to have semi-colons after k-v pairs in an object? This must be a Typescript syntax I'm unfamiliar with, but I'm not sure what it's called.

It's the equivalent of defining an interface, just without a name, so is following the syntax shown here:
interface CountInterface
count: number;
It's not actually a key-value pair, it's more a key-type pair. Due to the way typescript needs to work, this means that it is a set of statements (ending in semi-colon), and although it looks like an object literal, it's not.
So, yes, it is a "typescript thing", which allows for type-checking to take place.
