With statements

What happened?

The JavaScript with statement was used.

Why is this bad?

With statements might cause false positives when analysing unqualified identifiers. Also, with statements are marked as deprecated by the latest JavaScript standard.

Example

import QtQuick

Item {
    function f() {
        with (Math) {
            return PI
        }
    }
}

To fix this warning, replace the with statement with a destructuring property:

import QtQuick

Item {
    function f() {
        const { PI } = Math;
        return PI
    }
}
