Package Managers npm is a Web Development Basics pattern for one practical job. Learn the input, apply the smallest working syntax, check the output, then reuse the pattern in a real feature.
Why it matters
Package Managers npm matters because real Web Development Basics work needs consistent ways to load and render simple markup. Without this pattern, the feature becomes harder to change, test and review.
Real use
