Using in the context of Tinderbox Action code, an expression is a combination of values, variables, and operators that Tinderbox computes. This computation results in a new value. Commonly, that new value is then stored in a system or user attribute.
Used widely, in programming and data manipulation, 'expression' is a common concept. For example, an 'expression' can be a repeatable recipe use to calculate or derive information based on existing data.
In the context of Tinderbox, expressions are used to define values, set conditions, or perform computations to automate tasks and customise data handling.
A Tinderbox expression is normally a part of a complete Action code action (though in some edge cases the two are functionally the same).
