Tic Tac Toe

I finished all the winning conditions but I broke the game when I tried to make a condition when there is a tie so I'm guessing that may be the problem. I'm not sure if this code is correct:
(xoArray[0] === 'x' || xoArray[0] === 'o')&&(xoArray[1] === 'x' || xoArray[1] === 'o')
Unfortunately I ran out of time but I'll take another look at it tomorrow and if I get it working I will make the "You win" message better.

Here are some questions I have
Could you explain the nth-child and how you applied it to tr and td?
How does this line work exactly "xoClass = (xoClass === 'x') ? 'o' : 'x';"?
I think you explained both of these to me but I still don't quite understand.

jQuery

I finished up the jQuery lesson and here is a link to my moveme web page. Unfortunately I did not get any work done on my other projects because I was having a hard time with JavaScript but I should be able to next week.

JavaScript Objects II Notes

• Constructors are actually their own type of class
• A public method can return a private variable along with other private methods
• Use "var" in a class to make the variable private and "this" to make it public
•    this.age = age; (public)
     var bankBalance = 7500; (private)
• Inheritance is useful when 2 classes share similar properties
• "Child".prototype = new "Parent"()
• If you want a method to work with all the members of a class use "prototype"

• className.prototype.newMethod =
  
  function() {
  statements;
  };
  

• "Typeof" allows you to determine the type of a variable
• "hasOwnProperty" returns true or false whether or not an object has a certain property
• This is useful for if else statements
• "for in loops" are simplified for loops that look like this

• for (var properties in nyc){
      console.log(nyc[properties]);
  }

  • bracket notations can be used to print the values of an object

JavaScript

I started the lesson and finished about a third of it. The review was really nice and I have my notes in a separate post just because I want it all in one post and I should be able to post that tomorrow.

I fixed the positioning of the x's and o's but I still can't figure out how to prevent the x from changing to an o. I tried to put in a statement that would check but either it doesn't work or I am not putting it in the correct place.

if (!$(this).hasClass("o")) || (!$(this).hasClass("x")) {
