In Solidity, comments are used to add explanations and notes to the code. Comments are ignored by the compiler and do not affect the execution of the code. There are two types of comments in Solidity: single-line comments and multi-line comments.
Single-line comments start with “//” and continue to the end of the line.
// This is a single-line comment
Multi-line comments start with “/” and end with “/”.
/* This is a multi-line comment */
It’s important to use comments in your code to make it more readable and understandable for other developers. Comments can be used to explain the purpose of a contract, the logic behind a function, or to provide information about a particular line of code.
It’s also best practice to include comments on any complex, non-obvious, or controversial code as it can help to explain the intent of the developer and to make it easier to follow the code.
Overall, comments are an important tool for making your code more readable and understandable. They can help to document your code and make it easier to maintain and update in the future.
