Je kunt er ook meer over lezen op de <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia over omgevingsvariabelen</a>.

In veel gevallen is het niet direct duidelijk hoe omgevingsvariabelen nuttig zijn en hoe je ze moet toepassen. Maar ze blijven in veel verschillende scenario's opduiken als je aan het ontwikkelen bent, dus het is goed om er meer over te weten.
