Using null in QML

[Circuits]

Would it be considered bad practice in qml to initialize a var to null? For instance:

property var X: null

[fcarney]

I wouldn't think so.

property var x: null
property var y: undefined

Note that null is not the same as undefined.

@fcarney Is it even necessary in the QML world? Can I just leave it uninitialized like so:

property var X;

and tbh, I am initializing it as null but I am never running null checks when I use it...

no, it is undefined if you let it uninitialized.you can test it

     property var undefinedVar
    Component.onCompleted: console.log(undefinedVar)
// output  > qml: undefined
