Before You File a Bug Report Please Confirm You Have Done The Following...

[X] I have tried restarting my IDE and the issue persists.
[X] I have updated to the latest version of the packages.

What version of ESLint are you using?

8.57.0

What version of `eslint-plugin-svelte` are you using?

2.43.0

What did you do?

test('Counter', () => {
    let count = $state(0);
    let double = $derived(count * 2);

    count = 5;

    expect(double).toEqual(10);
});

What did you expect to happen?

I expect that no error / warning is shown. Especially it should be detected that "double" will change its value.

What actually happened?

At the "double" definition the following error is displayed:

ESLint: 'double' is never reassigned. Use 'const' instead.(prefer-const
