Exploring the Solidity syntax and JavaScript codes

This section will help us understand the Solidity syntax. We will explore the Solidity and JavaScript codes to understand our project in depth. This will also give us the power to alter the code to customize it to our needs.

Understanding the Solidity syntax

For understanding the syntax, let's take a look at the Solidity file MetaCoin.sol. The following screenshot will act as a guide so that we understand every line of code:

As you can see, every Solidity file begins with the definition of the Solidity version that you are currently using. In this case, that would be 0.4.17. This is immediately followed by the importing of the conversion library (commonly known as...
