a3f9 Mixins a3f9 , a3f9 HOC a3f9 , a3f9 render props, a3f9 and a3f9 Hooks a3f9 are 4 methods to a3f9 reuse parts

  • a3f9 There’s an implicit dependency between a3f9 the part and the a3f9 mixin a3f9 ( a3f9 Mixin a3f9 usually relies on the a3f9 precise methodology of the part, a3f9 however the dependency will not a3f9 be identified when the part a3f9 is outlined).
  • a3f9 There could also be conflicts a3f9 between a number of a3f9 mixin a3f9 (comparable to defining the a3f9 identical a3f9 state a3f9 area).
  • a3f9 Mixin a3f9 tends so as to a3f9 add extra states, which reduces a3f9 the predictability of the applying a3f9 and results in a pointy a3f9 improve in complexity.
  • a3f9 Implicit dependencies result in opaque a3f9 dependencies, and upkeep prices and a3f9 understanding prices are rising quickly.
  • a3f9 It’s troublesome to rapidly perceive a3f9 the conduct of parts, and a3f9 it’s crucial to totally perceive a3f9 all of the extension behaviors a3f9 that depend on a3f9 mixin a3f9 and their mutual affect.
  • a3f9 The tactic and a3f9 state a3f9 area of the part a3f9 itself is afraid to be a3f9 simply deleted as a result a3f9 of it’s troublesome to find a3f9 out whether or not a3f9 mixin a3f9 relies on it.
  • a3f9 Mixin a3f9 can also be troublesome a3f9 to keep up, as a a3f9 result of a3f9 Mixin a3f9 logic will ultimately be a3f9 flattened and merged collectively, and a3f9 it’s troublesome to determine the a3f9 enter and output of a a3f9 a3f9 Mixin a3f9 .

  • a3f9 Scalability restriction: a3f9 HOC a3f9 can not utterly exchange a3f9 a3f9 Mixin a3f9 . In some situations, a3f9 Mixin a3f9 can however a3f9 HOC a3f9 can not. For instance, a3f9 a3f9 PureRenderMixin a3f9 , as a result of a3f9 a3f9 HOC a3f9 can not entry the a3f9 a3f9 State a3f9 of subcomponents from the a3f9 skin, and on the identical a3f9 time filter out pointless updates a3f9 by way of a3f9 shouldComponentUpdate a3f9 . Due to this fact, a3f9 a3f9 React a3f9 After supporting a3f9 ES6Class a3f9 , a3f9 React.PureComponent a3f9 is offered to resolve a3f9 this drawback.
  • a3f9 Ref a3f9 switch drawback: a3f9 Ref a3f9 is lower off. The a3f9 switch drawback of a3f9 Ref a3f9 is sort of annoying a3f9 underneath the layers of packaging. a3f9 The operate a3f9 Ref a3f9 can alleviate a part a3f9 of it (permitting a3f9 HOC a3f9 to find out about a3f9 node creation and destruction), so a3f9 the a3f9 React.forwardRef API a3f9 API was launched later.
  • a3f9 WrapperHell a3f9 : a3f9 HOC a3f9 is flooded, and a3f9 WrapperHell a3f9 seems (there is no a3f9 such thing as a drawback a3f9 that can’t be solved by a3f9 one layer, if there’s, then a3f9 two layers). Multi-layer abstraction additionally a3f9 will increase complexity and price a3f9 of understanding. That is essentially a3f9 the most crucial defect. In a3f9 a3f9 HOC a3f9 mode There isn’t a a3f9 good answer.
