Npm 7 also supports workspaces, but doesn’t require the workspace root to be
private. This means the examples can be workspaces within the project, so the
entire project can be handled as one mono repository with a single lock file and
`node_modules` directory.
Also the readme has been updated with usage instructions.
Jest, eslint, and typescript-tslint-plugin were installed, but never used. Node
types were used for timers, but this is incorrect, as this code is supposed to
run in the browser.
