Defining the project scope means that you must have a clear vision and agreement on the outcomes of the project. This allows any deliverable of the project to remain on schedule.

Many people recently are complaining about bundler performance. But I don’t think any tool is going to solve performance problems. Bundlers can try innovative ideas such as multi-threading and improved caching, but you’re always going to hit a limit. If you’re having performance problems, it’s more likely because you’re not keeping tabs of what you’re importing, and haven’t considered splitting your project into multiple projects.
