\title With Statements
\brief With statements are strongly discouraged in QML.
\section1 With Statements
\section2 What happened?
The JavaScript \c{with} statement was used.
\section2 Why is this bad?
With statements might cause false positives when analysing unqualified identifiers. Also, \c{with}
statements are
\l{https://262.ecma-international.org/#sec-with-statement}{marked as deprecated by the latest JavaScript standard}.
\section2 Example
\qml
import QtQuick
Item {
function f() {
with (Math) {
return PI
}
}
}
\endqml
You can fix this warning by replacing the \c{with} statement with a destructuring property,
for example:
\qml
import QtQuick
Item {
function f() {
const { PI } = Math;
return PI
}
}
\endqml
\note You can find more replacement ideas
\l{https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/with?retiredLocale=de#examples}{here}.
