Avoid mutating ?? true to && true

[nicojs]

Summary

The above mutation always survives, we should not make it. I think.

Similar to #3339

@edi9999 maybe you want a go at this one again 😅

[nicojs]

Never mind. It's getting late I think. This is clearly not a mutation that always survives.

[edi9999]

?? can be converted to && in some occasions and change the behavior.

If for example I have this code :

function xxx(options) {
    const param = options.param ?? true;
    return param;
}

If I call xxx({param: 10}) it would return 10 before the mutation and true after the mutation
