Fizzbuzz js - extra credit - wondering if this is good or if more efficient way of doing?

I would stay away from using the single &, pretty sure it is better to use two &&

Found this on stackoverflow http://stackoverflow.com/questions/7310109/whats-the-difference-between-and-in-javascript

seems one & is called a bitwise AND and has to do with comparing numbers / binary stuff

single = is for assigning to a variable, two == work but probably should use 3 === this explains well http://www.w3schools.com/js/js_comparisons.asp

=== does value and type

the first reply in this is quick interesting! http://stackoverflow.com/questions/359494/does-it-matter-which-equals-operator-vs-i-use-in-javascript-comparisons

also pretty sure in the videos leading up to this task they said not to use == or !=

I see that I should have used 3! perhaps hadn't covered that when I did this task, also hadn't covered for loops

good to see your answer, thanks

We must think alike. After I found the same solution as you using WHILE, I was able to replicate it with a FOR loop:

for(var counter=1; counter < 101; counter=counter+1){
    if(counter % 3 == 0 & counter % 5 == 0 ) {
        console.log("fizzbuzz");    
    } else if (counter % 3 ==0) {
        console.log("fizz");
    } else if (counter % 5 == 0){
        console.log("buzz");
    } else {
    console.log(counter);
    }   
}

The only difference is that I'm using one "&" and not two "&" symbols to combine conditions in the first IF statement. If the code works both ways, I'm not sure what the difference is, but maybe the reason will become clear as I progress. In the meantime, I just tried "and" and "&" until I found the option appropriate to javascript's syntax. I also originally tried using just one "=" sign and couldn't figure out why the code wasn't working. Then I discovered that the code worked with "<" and ">" and recalled seeing the dual equal signs before in the forum. So I tested it, and my code finally worked! A single equal sign must have a special meaning that alerts the code that a variable is being assigned or renamed so I knew I needed a literal or escaped equal sign. (Luckily, I was already familiar with this concept more generally.) Once I was able to overcome the obstacles with my WHILE loop, I was able to get the FOR loop.

I appreciate the explanation and links! They were very helpful. The && versus & makes sense to me now, and it's clear that && is what is needed since we aren't dealing with binary comparisons. My understanding is increasing bit by bit (please pardon me for never resisting a pun). I understand the == versus === enough to know that === seems to be a safer and more straightforward comparison for most purposes. I don't recall any reference to the so called "evil twins" in the previous videos ("Intro to Programming" as it falls in the PHP track). So now I'm not sure if I simply missed it or if we arrived at the challenge from different places.

Hey, I did intro to programming in the front end web dev track, within JS. but as I finished it they had updated the course to have a new one called JS basics. so it may have been in that course that it talked about == and !=.
