Parameters
| Parameter | Type | Description |
|---|---|---|
expression |
Any | Required. The expression to evaluate. |
leftResult |
Any | Required. The value to return if the expression evaluates to true. |
rightResult |
Any | Required. The value to return if the expression evaluates to false. |
Return Value
The function returns leftResult if the expression evaluates to true according to truthiness rules, otherwise returns rightResult. Truthiness evaluation follows these rules: null is false; boolean values are returned as-is; 0 is false, any non-zero number is true; empty string "" is false, any non-empty string is true; empty arrays [] and empty objects {} are false. Both leftResult and rightResult are always evaluated, regardless of which is returned.
