What is replaced by the value added for the destination environment during deployment?

During deployment, the variable values are replaced with the corresponding values designated for the specific destination environment. This mechanism ensures that the values within the deployment package match the configuration and settings of the environment to which the package is being deployed. For instance, if a certain variable in a source environment holds a URL or an API key and that value needs to be different in the target environment, the deployment process will recognize the variable and substitute it with the correct value for the destination.

This process facilitates smooth transitions between different stages of development, such as from development to testing or from testing to production, ensuring that each environment's unique configurations are respected and applied correctly. Consequently, the deployment can complete successfully, reflecting the distinct elements required for the new setting. Thus, the emphasis on variable values is crucial in this context, as they define the real-time data that interacts with the deployed code.
