Day 2 - Comments and NatSpec

This is Day 2 of 30 in Solidity Series
Today I Learned About Comments and NatSpec Format in Solidity.

Solidity supports both C-style and C++-style comments, Thus −

  • Any text between a // and the end of a line is treated as a comment and is ignored by Solidity Compiler.
  • Any text between the characters /and/ is treated as a comment. This may span multiple lines.
// This is a Single Line Comment

/*

This is A Multi-Line Comment 
It can also Include Emojis 😃

NatSpec Format

Solidity contracts can use a special form of comments to provide rich documentation for functions, return variables and more. This special form is named the Ethereum Natural Language Specification Format (NatSpec).

/// This is NatSpec Single Line Comment
/// @title This is a Title
/// @author Author Name
/// @dev Please use this in this way

/**
This is NatSpec Multi Line comment
This is Line 2
And so on....
*/
