Understanding `Effect.try` with a Function that Throws an Error

const canThrow = (n: number) => {
  if (n === 5) {
    return Effect.succeed(n);
  } else {
    throw new Error("Number not 5");
  }
};
const tryCatch = Effect.try({
  try: () => {
    return () => canThrow(4);
  },
  catch: (error) => {
    return Effect.fail(`some error ${error}`);
  },
});
console.log(tryCatch);
