Types have no overlap, but i have defined the type so that it does in fact have overlap

This is the error that i am getting `This comparison appears to be unintentional because the types '"KVA"' and '"XYZ"' have no overlap.ts(2367)`` Why is this not working 🙂 ?

because the type of TYPE is not actually your union but the exact string "KVA" so it can never be "XYZ"

i also tried it with let but that does not change anything as ts knows that the value will never be redeclared i think this is only an example as it does not make sense to me why you would have conditions based on a hardcoded value TESTTYPE will always be "KVA" based on that condition so you could also just: 
const TESTTYPE = "KVA"
const TESTTYPE = "KVA"
