//Been seeing a lot of this lately in various repos. This is unnecessary because you're simply
//rethrowing the same error that would have been thrown anyway thus rendering your try/catch block useless:
try {
	//execute some code..
} catch(error) {
	throw error;
}

//The only reason to catch an error is to either handle that error or log it:
try {
	//execute some code..
} catch(error) {
	loggerInstance.error('Some error occurred performing some operation...', error);
	throw error;
}

//or handle the error by returning a value that can be used by the caller:
try {
	//execute some code..
} catch(error) {
	return someDefaultValue;
}
