<br>
* calldata is the encoded parameter(s) sent on functions by smart contracts to the evm (for example, through `abi.econde()`,`abi.econcdeWithSelector() for a particular interfaced function, or `abi.encodePacked()` for efficient dynamic variables).
* `selector()` generates the 4-bytes representing the method in the interface: this is how the evm knows which function is being interacted.
* each piece of calldata is 32 bytes long (64 chars), where 20 hex == 32-bytes
* types:
- static variables: the encoded representation of `uint`, `address`, `bool`, `bytes`, `tuples`
- dynamics variables: non-fixed-size types: `bytes`, `string`, dynamic and fixed arrays `<T>[]`
* opcodes are 1 byte in length, leading to 256 different possible opcodes. the EVM only uses 140 opcodes.
