React's true strength lies in "the ability to compose components into larger components." This increases code cohesion by keeping logic, styles, and markup together in one place. Nesting multiple conditions (isPending, !data, data) within JSX for rendering different states increases cognitive load and makes the code harder to read.
  • Extract the common UI structure (layout) into a separate Layout component.
  • Use early return for state-based UI instead of JSX conditionals.
