Programming: JQuery Questions

Recently been asked few programming questions, and the heck wasnt ready for those. The questions were 1. whats the difference between .parent() and closest() in JQuery, and surprise surprise I wasnt able to give an answer, all I can think about is parent(), is of course getting the parent of the element but wasnt sure whats the closest() function was. A simple search takes me to Traversing and there it is. I just had a look at the description and yep. closest(selector) takes an argument selector to look for the closest element and traverse to the tree all the way up the root html.

2. create a function isPalindrome($x), this one I just didnt know what palindrome means, went to search again and there it was, the term palindrome any text given and if reverse should be the exact same as the original. when I was cooking dinner.. just thought there might be a function the reverses the string and then match it against the original.meek .. too late.

3. (selector, selector, selector).fadeIn() how do you construct a function so they dont fade at the same time? Ugh another challenge when you are at the moment not using JQuery. Since I havent really delve into much in JQuery lately, top of my head just said just separate each one so they fade in order. Later that day I did a quick search “multiple selection”  and there it is the each() function, then I thought there must be a way to delay it for some milliseconds and there I went and look for the function there it was delay(milliseconds) chain them together with passing each(index) and voila .each(function(index) { $(this).delay(500*index).fadeIn(1000) }); would have been the answer again too late! lol

4. The last question I couldnt put together was to construct a regular expression, I can answer it but I just needed more time to pull up all my symbols expression using these: ^ $ * { } [] a-z 1-9 ? ! + ABC.  I know how to use them and what they means. Again out of time and too late.

Anyways Ive learned something new that day, which Im always happy about. Just so excited in the world of programming, I may not get a good result but it was definitely fun!
