attempt

function Result.attempt(unsafeFn: () => T): Result<T, unknown>

Wraps a function that may throw an exception in a Result. If the unsafeFn executes successfully, returns its result wrapped in Ok. If it throws an error, returns the error wrapped in Err.

Example

Result.attempt(() => 5);
// Ok<number>(5)

Result.attempt(() => {
    throw new Error("Something went wrong");
});
// Err<Error>(Error: Something went wrong)

Result.attempt(() => JSON.parse('{"valid": true}'));
// Ok<object>({valid: true})
