Cohesion & Coupling

Aim for HIGH cohesion (a class’s parts belong together) and LOW coupling (classes barely depend on each other). It’s the master dial behind every other principle. An animated lesson where the diagram draws itself as the design grows.

3 lessons, each with diagrams that draw themselves.

What you will learn

  • Two forces that shape every design
  • Low cohesion, the grab-bag
  • High coupling, the tangled web
  • Loosen it with abstractions
