I am a beginner in javascript and I have a question. This array represents the "dataState" in the forloop. But somehow I cannot access the id with "item.id" and so the first condition never triggers and in the else case, the item.id pops out as undefined. Any idea?

[
    {
        "name": "a",
        "secName": "b",
        "tel": "+ 123 737 159 028",
        "note": "qw",
        "id": "B_A"
    }
]

for(const item in dataState){
        console.log(item)
        if(item.id===state.secName.toUpperCase() + "_" + state.name.toUpperCase()){
          setId("11")
          console.log("green")
        }else{
          setId(state.id)
          console.log(item.id)
          console.log(dataState)
          console.log("red")
        }
      }
