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.

Underscore.js features and specs

• Utility Functions
  Underscore.js provides a wealth of utility functions for common tasks such as map, reduce, filter, and more, making it easier to perform operations on arrays, objects, and collections.
• Consistency
  The library offers a consistent API, which can make your code more readable and maintainable by providing a standard way to perform common programming tasks.
• Lightweight
  Underscore.js is lightweight compared to full-featured libraries like Lodash, which can be a benefit if you're looking to minimize your application's footprint.
• Browser Compatibility
  It supports a wide range of JavaScript environments, making it a good choice for projects that need to work across different browsers and Node.js.
• Quick to Learn
  Easy to pick up for developers with even a basic understanding of JavaScript, due to its straightforward documentation and familiar function names.

Possible disadvantages of Underscore.js

• Performance
  Underscore.js may not offer the same level of performance optimizations as more modern utility libraries like Lodash, potentially leading to slower execution for some tasks.
• Limited Functionality
  While it covers many basic utility functions, its feature set is not as extensive as Lodash or other similar libraries, which provide a broader range of capabilities.
• Outdated
  With the advent of ECMAScript 5 and later versions, many of the functions provided by Underscore.js are now natively available in JavaScript, reducing its necessity.
• No Modularization
  Underscore does not support modular builds in the same way Lodash does, meaning you might end up including the entire library even if you only need a few functions.
• Community and Maintenance
  While still maintained, Underscore.js has seen less active development and contributions compared to newer libraries, which could impact its long-term viability and support.
