Possible disadvantages of Sencha Ext JS

• Costly Licensing
  Sencha Ext JS is a commercial product with licensing fees, which can be expensive for small businesses and individual developers.
• Steep Learning Curve
  The framework is feature-rich and complex, meaning that new developers may find it challenging to learn and start using effectively.
• Large Library Size
  The extensive range of features and components leads to a large library size, which can be a concern for performance and load times.
• Lower Popularity
  Sencha Ext JS is not as widely used as some other frameworks like React or Angular, resulting in a smaller community and fewer third-party resources.
• Complex Integration
  Integrating Sencha Ext JS with other modern frameworks or libraries can be complex, requiring more effort to make them work together seamlessly.
• Limited Flexibility
  Ext JS enforces a particular structure and design philosophy, which might limit flexibility and creativity for developers who prefer a more modular approach.
• Performance Overhead
  The framework's extensive capabilities and features can sometimes introduce performance overhead, particularly in very high-performance or resource-constrained environments.

Possible disadvantages of Umbrella JS

  Being less popular than jQuery and other big libraries, Umbrella JS has a smaller community, potentially leading to fewer third-party plugins and community support.
