Detect if your code is running on an AWS Lambda server. 

The is-lambda npm package is designed to help developers determine if their code is running in an AWS Lambda environment. This can be particularly useful for writing code that needs to behave differently when run in a Lambda function versus other environments, such as on a local development machine or a different cloud platform. The package provides a simple interface to check the execution environment.

This feature allows developers to programmatically determine if their code is executing within an AWS Lambda environment. The code sample demonstrates how to use the is-lambda package to check the environment and print a message accordingly.
