dra1n

What it gives?

• Visual documentation

  • Discoverability (Easier to find existing components. Potentially works for designers too. As a result, we are saving time because we are not doing the same thing again and again)
  • Regression (Breaking design or API changes will be reflected)
  • Describes component API (And edge cases)
  • Hints to intended usage

• Faster design delivery (than having component embedded into the page)

• Early design feedback
