		#### Using the `\|\|` operator
		#### Using the `??` operator

		Instead of providing a second parameter, you may use the `\|\|` operator to handle default values. However, this may lead to problems with boolean values, e.g. if you want to use a default value of `true`:
		Instead of providing a second parameter, you may use the `??` operator to handle default values:

		```javascript
		// This will always evaluate to true, no matter whether ROOT is false or true.
		const isRoot = processenv('ROOT') \|\| true;
		const isRoot = processenv('ROOT') ?? true;
		```

		The underlying problem here is that when a value of `false` is given for the environment variable, the `\|\|` operator automatically falls back to the `true` keyword, hence the result will always be `true`.
		Please note that this is only true if you are using the `??` operator. If you are using the old-style `\|\|` operator instead, the previous line always returns `true`, no matter what the actual value of the `ROOT` environment variable is. To avoid this problem, either use the `??` operator or use the previously shown syntax using a second parameter to provide a default value.

		To avoid this problem, always use the previously shown syntax using a second parameter to provide default values.
