# tsc

This directory contains the code for the typescript compiler snapshot

There is currently A LOT of overlap between this code and the runtime snapshot
code in cli/js2.

This is intentionally ugly because there should be no overlap.

This directory ultimately should contain just typescript.js and a smallish
CompilerHost.
Reduce size of TypeScript Compiler snapshot (#6809) This PR is intentionally ugly. It duplicates all of the code in cli/js2/ into cli/tsc/ ... because it's very important that we all understand that this code is unnecessarily duplicated in our binary. I hope this ugliness provides the motivation to clean it up. The typescript git submodule is removed, because it's a very large repo and contains all sorts of stuff we don't need. Instead the necessary files are copied directly into the deno repo. Hence +200k lines.
