The pure Functions
Learn about pure functions in Solidity.
Understanding the pure functions
The pure functions are important in Solidity because they ensure that no state is read or updated within the function. They’re intended for deterministic calculations and are a necessary component of secure and predictable smart contracts. We’ll explore these functions, including their purpose, properties, and how to utilize them successfully in contracts.
Purpose of the pure functions
Within smart contracts, the pure functions serve a specific purpose:
Immutability: They ensure that no state variables are read or updated within the function. This immutability is critical for a smart contract’s integrity and predictability.
Determinism: Regardless of the environment or context in which they’re called, these ...
