poor performance on large files

[drvid]

Hi it just so happens I am using this on a very big HTML file (almost 10,000 lines).
When I type </ towards the bottom of the document, it can take up to 10 seconds to complete closing the tag. Sometimes the whole editor goes unresponsive even.

Yeah there's a lot of regex going on. Maybe we could investigate parsing backwards from the insertion point instead of right from the start? Idk how to do perf testing...

Maybe we could cache the stack of tags so we don't have to parse the entire document on every completion, or find a way to partially parse the document in the background in anticipation.

We could also investigate using a more performant parser than regex, but it's harder to add custom syntaxes eg. jsx mustache

I have the same issue. Using a javascript file with 2000 lines, typing gets really slow and the editor often freezes for a couple of seconds. I've disabled the plugin right now, as editing such files is a real pain. Hope to see this fixed as I like the plugin and use it all the time.
