Do you need math to be good in JS?

@coderamen Mostly basic math. Critical thinking skills and the willingness to persevere when problems become complicated.

@coderamen You just have to working on it religiously. It's rare that I do any more than basic math at work(Jr Developer).

ic thank @James-H33
btw it's there a easier way to understand and calculate remainder math answer? I still don't get it how 5%2 is remainder of 2...:(
i mean to get answer 2...

@coderamen So, in the problem 5 % 2; 1 should be your remainder. Basically the number 2 (in the case) is multiplied by itself until it can no longer be multiplied again without being over the number 5(in this case). So 2 * 2 = 4 with 1 being the remainder to get you to 5.

what if is 5 %3?

So, say to yourself like this "How many times can 3 be added by 3 to get close to 5 but not over?"
``// 3 *2 would give you 6 which is over 5 therefore 3 * 1 = 3 which then it takes 2 more to get to 5! So, 5 % 3 has a remainder of 2.``

``````
// Modulo Operator || Remainder Operator

50 % 4 = 2 // Behind the scenes 4 * 12 = 48 (add 2 more to get to 50)
24 % 7 = 3 // 7 * 3 = 21 (add 3 to get to 24)
37 % 9 = 1 // 9 * 4 = 36 (add 1 to get to 37)``````
Happy New Year by the way!

hi ! I've been wondering what this line of code is all about ? `app.use(bodyParser.urlencoded({extended:true}));`

@AmirBraham that is so when you pass a form you can grab the names and put them in a database or use the values someone types into it

express doesn't parse the POST request body (ex. the submitted form data) by default so you use bodyParser for that. The part that says ".urlencoded({extended: true})" just tells bodyParser that the submitted data will be a set of url-encoded key-value pairs. This make it suitable for parsing submitted form data. If you were writing a json REST api for example, you would use `bodyParser.json()`

@fang0rnz Hey, I believe the issue is that you're using ":nth-child" when you should be using ":nth-of-type"
