We have covered the basics of Solidity in this chapter. However, there are some topics that we haven't covered, which you can learn about with some self-study. For this, we recommend the following:

• Get an understanding of how string and hexadecimal literals are defined in Solidity. You can refer it online from Solidity documents at https://solidity.readthedocs.io/en/v0.5.0/types.html#string-literals.
• Understand how the conversions between different data types are supported in Solidity. You can refer it online from Solidity documents at https://solidity.readthedocs.io/en/v0.5.0/types.html?#conversions-between-elementary-types.
