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

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

    • Scalability restriction: HOC can’t utterly change Mixin. In some situations, Mixin can however HOC can’t. For instance, PureRenderMixin, as a result of HOC can’t entry the State of subcomponents from the skin, and on the identical time filter out pointless updates by means of shouldComponentUpdate. Due to this fact, React After supporting ES6Class, React.PureComponent is offered to resolve this drawback.
    • Ref switch drawback: Ref is lower off. The switch drawback of Ref is sort of annoying below the layers of packaging. The operate Ref can alleviate a part of it (permitting HOC to study node creation and destruction), so the React.forwardRef API API was launched later.
    • WrapperHell: HOC is flooded, and WrapperHell seems (there isn’t any drawback that can not be solved by one layer, if there may be, then two layers). Multi-layer abstraction additionally will increase complexity and price of understanding. That is essentially the most vital defect. In HOC mode There isn’t a good answer.

    • Reverse inheritance Inheritance Inversion.
