WebMapping is a hash table in Solidity that stores data as key-value pairs, where the key can be any of the built-in data types, excluding reference types, and the value of the data type can be any type. Mappings are most typically used in Solidity and the Ethereum blockchain to connect a unique Ethereum address to a corresponding value type. orbital wall fracture precautions
