Power Fx function

And && — Power Fx function reference

All conditions true.

Syntax

powerfx

And( Logical1, Logical2, ... ) / Logical1 && Logical2

powerfx

And(Active, Approved)

→ true / false

powerfx

And(txtEmail.Text <> "", IsMatch(txtEmail.Text, Match.Email))

powerfx

!IsBlank(txtName.Text) && Value(txtAge.Text) >= 18

And() and && are interchangeable — && reads better for two or three terms, And() reads better for a long or dynamically-built list.
Power Fx does not guarantee short-circuit evaluation the way some languages do — do not rely on ordering to avoid evaluating a risky second condition; guard with IsBlank/IfError first instead.
