Definition

A comment is a text written close to any piece of code to better describe what it does to other developers.

Use cases and Examples

🚫 Wrap Code📋 Copy
01: 1 var count = 0;
02: 2 for(var i = 0; i<10; i++) {
03: 3    count++;
04: 4 }
05: 5 console.log(count); // count is 10; 

Line 5 of the Javascript code above has a comment ie: count is 10 which tells the reader what the output of the console log statement will be.

Summary

Sometimes a developer can take commenting too far when they rather choose to comment on a poorly written code instead of just fixing it.
