If you were to try and use the environment variable directly, eg. echo $YOUR_VAR you will get a warning stating that the variable is not defined.

You will have to use the builtin getenv() PHP function to get the value of the environment variable first, and then use that value in your code:

$your_var = getenv('TEST_VAR');
echo $your_var;

The same would go for JavaScript functions with the process core Node module that gives you access to the environment variables thanks to the env property (eg: process.env['your_env']).

Hope that this helps!
