// This is a single-line comment
/*) at the beginning and the asterisk and forward slash (
*/) at the end. For example:
/* This is a multi-line comment It can span multiple lines */
Comments are particularly useful when you have a section of code that is difficult to understand or has a specific purpose. For example, if you have a block of code that performs a complex calculation, you can use a comment to explain what the calculation is doing and why it is necessary.
//Performing a complex calculation var result = (a*b)/(c+d);
Another good practice is to use comments to add information about the author, the version, and the last modification date of the code. It helps to understand who made the changes and when it was made.
//Author: John Doe //Last modification: 22/01/2022
You can also use comments to temporarily disable a section of code. This is useful when you are testing or troubleshooting your code and want to quickly disable a specific section without having to delete it.
//Disabling this section of code //var result = (a*b)/(c+d);
