33: Using type()

type() is a function in Solidity that allows developers to query the type of a variable. This can be a useful tool for debugging, as it can help developers identify issues with their code. Here are some examples of using type()

• Example 1

uint256 myInteger = 5; 
type(myInteger);

This will return uint256, as myInteger is declared as a uint256 variable.

• Example 2

string myString = "Hello World"; 
type(myString);

This will return string, as myString is declared as a string variable.

• Example 3

mapping(uint256 => uint256) myMapping; 
type(myMapping);

This will return mapping(uint256 = uint256), as myMapping is declared as a mapping from uint256 to uint256.
