Conversion of js true and false empty array

let obj ={
        a :true,
        b:[]
    }
if(obj.a && obj.b){
  console.log(324)
}
//324 obj.b

//
obj.b => [] => Boolean([]) => true
//
[]===[]
//false

< H2 > add: how can I modify it if I want to implement the usual function that only executes 1 for true? This array is sometimes a non-empty array < / H2 >
