JS question: does list have value

Good day honorable adobe forum members,

I am looking for the method to use to check if a value is in a list

i.e.:

var list = ["A","B","C"]

if ("a"  in list) {
//dothings
}

Hoe does one do this effectively?

Thank you in advance for any and all trouble to be taken

I see I typed "a" instead of "A" , I hope this doesn't cause confusion (the example should say "A")
