A developer needs to create a variable to store the value of an email address. Which variable property or field is optional?

In the context of variable creation, the property or field that is optional is the default value. When defining a variable, the developer must specify both the type and the name to ensure that the variable is properly recognized and can be utilized as intended in the automation process.

The type of the variable determines what kind of data it can hold, while the name is necessary for referencing that variable throughout the automation. On the other hand, setting a default value is not mandatory. If a default value is not provided, the variable will simply be initialized without a predefined value, allowing it to be set or modified later in the workflow.

Scope also plays a crucial role in variable visibility but is typically set by the developer based on where the variable needs to be accessed within the automation. Therefore, among all the fields provided, the default value is the only one that can be omitted without affecting the core functionality of the variable.
