Underscore.js VS EJS

• 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

• 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• Outdated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.

• Simplicity
  EJS is easy to learn and use, especially for developers who are already familiar with JavaScript. The syntax is straightforward, making it a good choice for quick application development.
• JavaScript Integration
  Since EJS templates are JavaScript files, you can seamlessly integrate JavaScript code, making it easy to manipulate data and use familiar JavaScript functions.
• Lightweight
  EJS is a lightweight template engine, which makes it an optimal choice for applications where performance and simplicity are critical.
• Flexibility
  Allows for the embedding of plain JavaScript within the templates, giving developers the flexibility to add logic directly in their HTML.
• Partial Templates
  Supports partials, which help to reuse code snippets across different views, promoting DRY (Don't Repeat Yourself) principles.
• Server-Side Rendering
  Supports server-side rendering, which can improve performance by reducing the amount of client-side processing needed.

Possible disadvantages

• Limited Functionality
  Compared to more feature-rich template engines like Handlebars or Pug, EJS offers limited functionalities which might be a drawback for large, complex projects.
• Debugging
  Debugging EJS templates can sometimes be challenging. Errors within templates can often be vague, making it difficult to trace the root cause.
• Maintenance
  Embedding a lot of JavaScript within templates can make the code harder to read and maintain, especially as the complexity of the application grows.
• Performance Overhead
  For very large and complex templates, EJS can introduce a performance overhead compared to more optimized template engines designed for high performance.
• Community and Support
  While EJS has a reasonable user base, the community and support may not be as extensive as more popular alternatives like React or Vue.js.
