QuerySelect is named as QuerySelector in the official documentation
I'm using Type Script, and there's already the types for the official DOMParser types.
Here are the types for QuerySelector function:
And this is the official documentation https://developer.mozilla.org/en-US/docs/Web/API/Element/querySelector
The problem is that for some reason in this package we have querySelect instead of querySelector, and this fact breaks type checking:

Any reason for having a different name? Can this be fixed?
similar issue with getElementsByAttribute in typescript (although code works it does not compile in ts)
const doSomethingWithDocument = (document: HTMLDocument): void => {
const styledElements: HTMLCollectionOf<Element> = document.getElementsByAttribute('style');
...
error TS2339: Property 'getElementsByAttribute' does not exist on type 'HTMLDocument'.
Slightly off topic, but I tried yarn add --dev @types/react-native-html-parser and it didn't work. Were you guys able to get TypeScript working with this package?
Created advanced-html-parser and added more feature and typescript support. Please check it out.
