 - Consider the performance / size impact of the changes, and whether the bug being fixes justifies the cost. If the bug being fixed is a very niche edge case, we should try to minimize the size / perf cost to make it worthwhile.
 
   - Is the code perf-sensitive (e.g. in "hot paths" like component updates or the vdom patch function?)

     - If the branch is dev-only, performance is less of a concern.
 
   - Check how much extra bundle size the change introduces.

 **The examples below will be using the `nr` command from the [ni](https://github.com/antfu/ni) package.** You can also use plain `npm run`, but you will need to pass all additional arguments after the command after an extra `--`. For example, `nr build runtime --all` is equivalent to `npm run build -- runtime --all`.
 
+The `run-s` and `run-p` commands found in some scripts are from [npm-run-all](https://github.com/mysticatea/npm-run-all) for orchestrating multiple scripts. `run-s` means "run in sequence" while `run-p` means "run in parallel".
