An example of an AI chatbot conversation about environment variables in various programming languages.
How do environment variables work in different programming languages?
Environment variables are key-value pairs used to configure applications. They can be accessed differently depending on the language.
Can you give me examples for Python and JavaScript?
In Python, you can use the os module: import os; value = os.getenv('MY_VAR'). In JavaScript, you can access them via process.env.MY_VAR.
What about in Java?
In Java, you can use System.getenv("MY_VAR") to retrieve the value of an environment variable.
Are there any best practices for using environment variables?
Yes, it's best to keep sensitive information like API keys in environment variables and not hard-code them in your source code.
