Given that TypeScript limits decoration to class, method, property, or setter/getter due to hoisting restrictions, is there a workaround to decorate a raw function? Perhaps an alternative decoration mechanism could be implemented or a custom solution created to bypass TypeScript's constraints. Appreciate any insights.
While not specifically outlined in the "TypeScript rules," this issue pertains to JavaScript. At present, using @decorator for functions is not syntactically feasible. However, at its core, a function decorator essentially functions as a higher-order function that envelops the decorated function.
The closest workaround involves creating a function wrapper:
function foo() {
return "asd";
}
const wrap = (func: () => void) => {
const wrapped = () => {
console.log("wrapped");
return func();
}
return wrapped;
}
console.log(wrap(foo)());
