Overall verdict
Why this product is good
Recommended for
RequireJS is recommended for projects that are already using it, especially if the project is large and refactoring to a different module system would be resource-intensive. It can also be suitable for legacy web applications that have complex dependency chains which have been built with AMD (Asynchronous Module Definition) patterns. However, newer projects are better served with modern bundlers and native ES6 module syntax.
