Use jQuery and JSON to render the page!

Meet Mr. Fox -- JSON to HTML Challenge

Your goal is to fill in the blanks in Mr. Fox's profile using jQuery, and data from a JSON object.

Setup

Please clone this repo.

Open index.html in your browser, and launch your Chrome Javascript Console.

You will be coding in the files scripts/app.js and index.html.

Please note that the JSON object is accessible by typing data. Each time you refresh it will change a little bit (just to keep you on your toes!).

Pre-Requisite Skills

• Getting Values from Objects and Arrays
  • Using Bracket Notation
  • Using Dot Notation
• Looping over Arrays/Lists
  • Using the current index of the loop
• Combining Strings using Concatination
  • Creating HTML strings

Looping Lists

Often we want to do this same thing multiple times, but with values at different indexes.

var list = ["a", "b", "c"];
for(var i=0; i<list.length; i++){
  console.log(i, list[i]);
}
// 0 a
// 1 b
// 2 c

We can do the same thing with the powerful forEach Array method:

var list = ["a", "b", "c"];
list.forEach(function(value, i){
    console.log(i, value);
})
// 0 a
// 1 b
// 2 c

What is JSON?

JSON is a convenient format for transferring data. It is supported in many languages, not just Javascript!

Although Javascript Objects and JSON have a lot in common, JSON follows a slightly more strict format.

Here is an example of a JSON object:

{
    "key": "value"
}

We can assign the object to a variable o.

var o = {
    "key": "value",
    list: ["a", "b", "c"]
}

To access values, we need to know the name of the key. We can use either dot notation or bracket notation:

// dot notation
o.key;      //=> "value"

// bracket notation
o["key"];   //=> "value"
o['key'];   //=> "value"

Sometimes you'll need to "drill" down into an object to get the value you want.

**How would you get the value `"c"`?** (Click Here)

```js o.list[2]; // "c" o.["list"][2]; // "c" o.['list'][2]; // "c" o.['list']['2']; // "c" o.['list']["2"]; // "c" ```

But note that o.list.2 will never work. Why is that?

What is Concatination?

When we combine strings together, it's known as "concatination". Here's an example:

"1" + "1";                  //=> "11"
"what's" + "up?";           //=> "what'sup?"
"hello" + " " + "world";    //=> "hello world"

**""What'll happen when you "quote" a quote?", he asked, helplessly"** (Click Here)

```js 'this "works"' "and this'll work" 'but don't do this!' // SyntaxError "He said \"don't\" do this, but I'm clever" // escape inner quotes with forward slash ```

We can create HTML strings by simpling creating a string containing HTML:

var p = "<p>simple paragraph</p>";

var words = "words words words";
var dynamic_paragraph = (
    "<p>" +
        words + "!" +
    "</p>"
);

dynamic_paragraph //=> "<p>words words words!</p>"
