swapObjectKeys¶

Overview¶

Swap the values of two keys on an object, but only if the value is defined

@example swapObjectKeys( { x: 4,y: 3 }, 'x', 'y' ) -> { x: 4, y:3 } swapObjectKeys( { x: 4 }, 'x', 'y' ) -> { y:4 } swapObjectKeys( { x: 4, y: undefined }, 'x', 'y' ) -> { x: undefined, y:4 } swapObjectKeys( { otherStuff: 'hi' }, 'x', 'y' ) -> { otherStuff: 'hi' }
