equalTo
Validates that the object value is equal to the expected value.
This function creates a validation rule that checks if the current object value equals the value returned by the expected function using the == operator. The comparison is performed each time the validation runs, allowing for dynamic expected values.
Usage:
// Password confirmation validation
rules<String> {
equalTo({ passwordField.value }) { "Password confirmation must match the password" }
