I prefer semicolors, they also help avoiding certain pitfalls in JavaScript/TypeScript, such as the following code sample:
```js
const xyz = "test"
(something.else as string) = "another"
```
This results in a TypeError: "test" is not a function, this is because js thinks we are trying to call the string "test" as a function.
To fix this it requires a `;` somewhere before the `(`, such as `;(something ... ` which in my opinion is ugly and less clean overall.
