The calldata Storage
Explore the concept of calldata storage in Solidity, focusing on its immutable and temporary nature. Understand how calldata differs from memory, its use in external functions, and best practices for handling arrays and structs to optimize smart contract efficiency and gas costs.
We'll cover the following...
calldata is recognized as the third type of data location in Solidity. It operates similarly to memory by serving as a temporary storage space. Although calldata is temporary storage, it differs slightly from memory. The primary distinction is that once function arguments are supplied, they can’t be changed inside the function because calldata is nonmodifiable storage. It’s less expensive than memory and is mostly utilized with external function types, which is the second significant distinction.
calldata is often utilized with external functions, and the this keyword allows us to invoke a function that’s declared with the external keyword inside the contract.
