Cases when Go does not work

1. Case: Lack of libraries and frameworks
   Go, as a relatively young programming language, may not have as extensive a library ecosystem as more established languages like Python or JavaScript. This can be a limitation when working on projects that require specific libraries or frameworks that are not available in Go.
2. Case: Garbage collection overhead
   Go uses a garbage collector to automatically manage memory. While this provides convenience to developers, it can introduce overhead in terms of memory usage and performance. In scenarios where low latency and high throughput are critical, such as real-time systems or high-frequency trading, the garbage collector’s impact on performance might be a concern.
3. Case: Lack of generics
   Go does not currently support generics, which can make writing certain types of code more cumbersome. Generics allow developers to write reusable, type-safe code that can work with different data types. Without generics, developers may need to resort to writing boilerplate code or using type assertions and type switches, which can be less efficient.
4. Case: Limited support for concurrent programming patterns
   While Go has built-in support for concurrency through goroutines and channels, it may not provide the same level of flexibility and expressiveness as other languages that have more mature concurrency models, such as Erlang or Akka. This can be a limitation when working on highly concurrent systems or when implementing complex concurrency patterns.
5. Case: Lack of inheritance
   Go does not include traditional class-based inheritance like some other languages. Instead, it relies on composition and interfaces to achieve code reuse and polymorphism. This can be a challenge for developers coming from backgrounds where inheritance is heavily used, as it requires a different mindset and approach to structuring code.
