First, it's important to understand what events do. When you call events, they cause the arguments to be stored in the transaction’s log, which is a special data structure in the blockchain.

They allow smart contracts to index variables in order to rebuild the storage stage. You can use the indexed variables to long blockchain data serverside.

Events also help to automatically update the user interface. By tracking events, you can change the front end of your dApp when a certain action has occurred.

Finally, events allow for the testing of specific variables. By tracking events, you can better bugtest and improve your dApp!
