without the whole code, it’s difficult to say anything about a snippet of it

let prime = 2,

max = 1;

while (prime <= number) {

if (number % prime == 0) {

max = prime;

number = number / prime;

} else prime++; //Only increment the prime number if the number isn’t divisible by it

}

return max;

}

`max`

is declared as a variable, alongside with `prime`

in the first statement:

```
let prime = 2, // line ends with comma!
max = 1;
```

This is the same as:

```
let prime = 2; // line ends with semicolon
let max = 1;
```

As for the second question, `max`

is repeatedly reassigned in the while loop, so that when the loop ends because the condition isn’t true anymore, `max`

will have the value of the last (and therefore biggest) factor.

ohhh I get it now, thank you so much! didn’t know that syntax part of comma

It’s not very common to declare variables like that, I for instance never use that syntax but always declare my variables with their own keywords on their own lines - it’s just more readable.
