In coding, error handling is a crucial element. Creating code that returns clear errors at the appropriate time helps in analyzing problems and deriving improvement measures when issues occur. This guide explains error handling in Solidity.

Reference types refer to the memory location where the value is stored, rather than the value itself. Unlike value types, where the value of the data is stored directly in the variable, reference types store only a reference to the location of the data. Reference types hold the position of data in memory, allowing memory usage to be optimized regardless of the data's size. Mapping types are data structures that store key-value pairs.

In Solidity, there are types like value types, reference types, and mapping types. Value types are used to define numerical and string types. In value types, the values are stored directly.

From Day 7 onwards, we will explain the basic syntax of Solidity. As a development tool, we will use Remix (an online IDE environment), which was introduced as basic tools of web3. First, we will start with development using Remix and learn about the basic structure of Solidity programs. Let's delve into the explanation.
