getAllIndexesOf [](start = 12, length = 15)
I think you could likely do this with regexs?
const beginReg = /\begin/g;
const endReg = /\end/g;
while (result = beginReg.exec(input)) {
result.index is index of match
beginReg.lastIndex is next match

Did you take a look at how Jupyter does this? The equation matching looks more complex to me.

Here is what you want.

Looks like we might need to check licensing as well.

Started using Regular Expressions instead of indexOf Added unit tests

I think this would have issues with mismatched begin / end pairs. The code is assuming that an equal number of \begin and \end matches were found, but you could have valid markdown with just those strings in it.
I think it's worth taking a look at this regex that I linked to see if it breaks out latex bits from a markdown block.
it now includes the opening anc closing brackets, with whatever name the user chooses. Also, the code will run only if the amount of indexes are the same.

This is not required in typescript.
