Good evening good folks! Can someone explain the below to me? I haven’t given it that much thought so maybe the answer is trivial…or not?

```julia
julia> [[1,2],[3,4]] == [[1,2],[3,4]]
true

julia> [[1,2],[3,4]] !== [[1,2],[3,4]]
true

julia> [[1,2],[3,4]] !== [[1,2],[3,5]]
true

julia> [[1,2],[3,4]] == [[1,2],[3,5]]
false

```

You are looking for `!=` rather than `!==`. The two mean different things, as do `==` and `===`.

True! Just realized 🙂 Easy to get them mixed up.
