If a function is stored in an array item, how can I gain access of the array's current index value inside the function?
For example, how can I set my function in order to get results similar to this?
arr['hello'](); // function returns 'hello'
arr['world'](); // function returns 'world'
arr[123]() // function returns 123
Unless you know in advance which specific properties will be used, you'll need a Proxy.
const prox = new Proxy(
{},
{
get(_, prop) {
return () => prop;
}
}
);
console.log(prox[123]());
console.log(prox.hello());
console.log(prox['world']());Since you have some non-numeric properties, you shouldn't use an array.
