In this chapter, we covered exception handling and events. These are important topics in Solidity, especially when writing any serious decentralized applications on the Ethereum platform. Exception handling in Solidity is implemented using three functions: assert, require, and revert. Although they sound similar, they have different purposes, which were explained in this chapter with the help of examples. Events help us write scalable applications. Instead of continuously polling the platform for data and wasting resources, it's better to write events and then wait for them to execute functions asynchronously. This was also covered in this chapter.
In the next chapter, we will focus on using Truffle, one of the most popular development ...
