Functions, Modifiers, and Fallbacks
Solidity is maturing and providing advanced programming constructs so that users can write better smart contracts. This chapter is dedicated to some of the most important smart contract constructs, such as functions, modifiers, and fallbacks. Functions are the most important element of a smart contract after state variables. It is functions that help to create transactions and implement custom logic in Ethereum. There are various types of functions, which will be discussed in depth in this chapter. Modifiers are special functions that help in writing more readily available and modular smart contracts. Fallbacks are a concept unique to contract-based programming languages, and they are executed when a function ...
