Is there a "if then" component to do calculation based on evaluation for each item within a list?

Assume I have a list A of 1 and 0 values, how do I change it to a new list B in which the value of a item is x if the same item in list A is 1, otherwise, the value of an item in list B is y if the same item in list A is zero?

Is there a "if then" component to do this?

Thank you!

Try "Evalute" or "Expression" component with "If" function. Best.

Dear Hyungsoo, thank you very much for the advice!

Great to learn the function of the expression component.

Pro-tip, if x is already a boolean, you can just type If(x, 24, 99)

Thank you very much, Dear David, for the Pro-tip!

Too much to learn from the community the diverse functions of GH.
