QtQml: Avoid infinite recursion in Array.join 2025-07-01T10:22:41+00:00 Fabian Kosmale fabian.kosmale@qt.io 2024-04-16T10:32:31+00:00 8b988a8fae2e5fb1889269018be132014fc3b464 So far, self-referencing arrays can lead to infinite recursion in Array.join. The standard allows us to throw an exception in this case, just like we already do in ObjectPrototype.toString(). This is not what browsers do, but arguably they are diverging from the spec.
