Analyze the code snippet:

let counter = 0;
let userName = "John";

After declaring a `counter` variable, we want to put a short comment with information about what the variable is used for. To do this, we modify the line declaration to the form:

// let counter = 0; user visit counter
let counter = 0; // user visit counter
let counter = 0; /* user visite counter
let counter = 0; # user visite counter

Answers Explanation & Hints:

To put a short comment with information about what the counter variable is used for, you can modify the line declaration in the following ways:

let counter = 0; // user visit counter

// let counter = 0; user visit counter
let counter = 0;

Both of these modifications achieve the desired result by adding a comment next to the declaration of the counter variable. It provides information that the variable is used for counting user visits.

Note that in JavaScript, single-line comments start with //, and multi-line comments are enclosed between /* and */. The # symbol is not used for comments in JavaScript.
