Just like the picture shows above.

I use the latest JuMP, and I turn off the Missingrefs suggested from [https://discourse.julialang.org/t/missing-reference-warnings-with-julia-in-vs-code/31321/7](https://discourse.julialang.org/t/missing-reference-warnings-with-julia-in-vs-code/31321/7)

And the problem is solved. Variables defined in the above method do not have code hint. 😂
