Why this code doesn't work:
let [kgFormValues, setKgFormValues] = useState<KgFormValues>(getKgFormValues());
Error: ReferenceError: Cannot access 'kgFormValues' before initialization
But when removing the parentheses works:
let [kgFormValues, setKgFormValues] = useState<KgFormValues>(getKgFormValues);
function getKgFormValues() {
return {
...
};
}
In order to get this to work, you must call the function after it's declared.
For example:
function getKgFormValues() {
return {
...
};
}
// now you can use it, as such:
let [kgFormValues, setKgFormValues] = useState<KgFormValues>(getKgFormValues);
