React Native is Written in Dynamically-typed Language
Your development team might tackle a few issues in the process of product creation. In contrast to Swift or Kotlin, JavaScript is a dynamically-typed programming language, which means it does not enforce any parameters to functions and variables. In such a scenario, a variable might be anything. To prevent such cases, there are a set of standards and guidelines developers need to follow. But, fortunately, there is Typescript to aid you in such situations.
Lack of Some Native Modules
While developing custom solutions, your team might need to insert the parts of native code into your product. In this case, you might end up having several codebases instead of a single one, which will demonstrate substantial differences in behavior and appearance. However, these are minor cases that do not often appear, so you are unlikely to face this issue.
