26. **RisingStack/

1. Overview: MobX is a simple, scalable, and battle-tested state management library for JavaScript applications.

2. Code Example:

import { observable, action } from 'mobx';

class CounterStore {
  @observable count = 0;

  @action increment = () => {
    this.count++;
  };
}

3. Pros:

   • MobX provides a straightforward and reactive approach to state management, making it easy to manage complex application state.
   • MobX has a small API surface and is highly performant, making it a great choice for large-scale applications.
   • MobX is framework-agnostic, allowing it to be used with various JavaScript frameworks, including React, Vue, and Angular.

4. Cons:

   • MobX may have a steeper learning curve compared to some other state management libraries, especially for developers new to reactive programming.
   • MobX's use of decorators can be a point of contention, as some developers prefer a more explicit approach to state management.
   • MobX may not be as well-suited for simple applications with limited state, as the overhead of setting up the reactive system may be overkill.
