• Minification
  UglifyJS effectively reduces the file size of JavaScript by removing whitespace, shortening variable names, and eliminating unnecessary code, which can lead to faster load times in web applications.
• Maturity and Stability
  As a mature and well-established tool, UglifyJS has a long history of usage and a strong community, making it a reliable choice for JavaScript minification with less risk of encountering severe bugs.
• Customization
  UglifyJS offers various options and configurations that allow developers to control the minification process, such as toggling specific optimizations and preserving certain comments.
• Compression
  Besides minification, UglifyJS provides compression options which further optimize the JavaScript code by evaluating constant expressions and removing unreachable code.

Possible disadvantages

• Source Mapping Complexity
  Generating source maps with UglifyJS can sometimes be complex and might not always accurately map minified code back to the original source, complicating debugging efforts.
• Transformations Side Effects
  Some of the aggressive transformations made by UglifyJS could potentially introduce bugs if the original code relies on exact syntax structure or has side effects that depend on expression evaluation order.
• Limited ES6+ Support
  Historically, UglifyJS has lagged in support for newer ECMAScript features compared to other modern minifiers, which might cause issues when dealing with ES6+ syntax without transpiling it first.
• Error Diagnosis
  When errors occur during the minification process, UglifyJS may not always provide clear or detailed error messages, which can make it difficult to diagnose and fix issues.
