i have been spend an hour in order to find the difference of Module and Block function but failed. if i regard this two function as a black box, it seems their function is the same . Could anyone share me a example to explain the difference of them.
The documentation discuss Module versus Block [here][1]
Module
Block
Thank you, Eric. i still can not distinguish them.however, your general advice gives a rule which i can follow in future. Thank you!
