This commit changes the build process in a way that preserves already registered ops in the snapshot. This allows us to skip creating hundreds of "v8::String" on each startup, but sadly there is still some op registration going on startup (however we're registering 49 ops instead of >200 ops). This situation could be further improved, by moving some of the ops from "runtime/" to a separate extension crates. --------- Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> |

How to upgrade TypeScript.
The files in this directory are mostly from the TypeScript repository. We currently (unfortunately) have a rather manual process for upgrading TypeScript. It works like this currently:
- Checkout denoland/TypeScript repo in a separate directory.
- Add Microsoft/TypeScript as a remote and fetch its latest tags
- Checkout a new branch based on this tag.
- Cherry pick the custom commit we made in a previous release to the new one.
- This commit has a "deno.ts" file in it. Read the instructions in it.
- Copy typescript.js into Deno repo.
- Copy d.ts files into dts directory.
- Review the copied files, removing and reverting what's necessary
So that might look something like this:
git clone https://github.com/denoland/TypeScript.git
cd typescript
git remote add upstream https://github.com/Microsoft/TypeScript
git fetch upstream
git checkout v3.9.7
git checkout -b branch_v3.9.7
git cherry pick <previous-release-branch-commit-we-did>
npm install
