How do I use dotenv variables in different programming languages?

You can use dotenv variables in languages like JavaScript, Python, and Ruby by loading them from a .env file.

Can you show me an example in JavaScript?

Sure! In JavaScript, you can use the 'dotenv' package. First, install it using npm, then require it in your code like this:

require('dotenv').config();
const myVar = process.env.MY_VARIABLE;

What about in Python?

In Python, you can use the 'python-dotenv' package. Install it via pip and use it like this:

from dotenv import load_dotenv
import os

load_dotenv()
my_var = os.getenv('MY_VARIABLE')

Are there any other languages that support dotenv?

Yes, many languages support dotenv, including Ruby, Go, and PHP. Each has its own library for loading environment variables.
