Clean Architecture (2022 H2)

Good architecture:

• good architecture = allow changes w/ flexibility + delay decision

Business rules:

• Entities: pure; small sets of critical business rules. Should be most independent & reusable. Can be an object with methods or data structures & functions
• Use case: not as pure; is an object. contains data elements & operations.
• Entities are lower level than (don’t depend on) use cases since use cases are closer to inputs/outputs.
• Entities & use cases are 2 layers

'use strict';

// CASE 1: The object is mutable and the variable can be reassigned.
let o1 = { foo: 'bar' };

// Mutate the object
o1.foo = 'something different';

// Reassign the variable
o1 = { message: "I'm a completely new object" };
