⏯ How to reproduce:

1. Use Node 10
2. git clone --branch 21-add-typescript-support git@github.com:theqp/MyEtherWallet.git
3. Change typescript to 4.2.2 (it would work otherwise)
4. npm i
5. echo "" > package-test.js && NODE_OPTIONS="--max-old-space-size=4096" npm run build
6. Wait for the crash :D

Bắt đầu bằng cách tái hiện bản build Node 10 bằng branch MyEtherWallet được liệt kê, TypeScript 4.2.2 và lệnh npm run build. Kiểm tra các mục stack parseList và parseSourceFileWorker trong node_modules/typescript/lib/typescript.js, cùng với cấu hình memoryLimit của ForkTsCheckerWebpackPlugin. Được xem là hoàn tất khi bản build 4.2.2 hoàn thành mà không làm cạn heap JavaScript và hồi quy vẫn được bao phủ.
