Ans. Node.js is known for its asynchronous, non-blocking nature, making it ideal for building highly scalable and efficient applications, particularly for real-time applications like chat and gaming platforms.
.NET also provides good scalability and performance, especially for enterprise-level applications, but may require more resources compared to Node.js.
PHP can build scalable applications, but its performance might be comparatively lower than Node.js and .NET for certain use cases.
