With Statements

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
         }
     }
 }

You can fix this warning by replacing the with statement with a destructuring property, for example:

 import QtQuick

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