"description": [
"JavaScript objects are flexible because they allow for <dfn>Data Structures</dfn> with arbitrary combinations of <dfn>strings</dfn>, <dfn>numbers</dfn>, <dfn>booleans</dfn>, <dfn>arrays</dfn>, <dfn>functions</dfn>, and <dfn>objects</dfn>.",
"Here is an example of a complex data structure:",
"Sometimes you may want to store data in a flexible <dfn>Data Structure</dfn>. A JavaScript object is one way to handle flexible data. They allow for arbitrary combinations of <dfn>strings</dfn>, <dfn>numbers</dfn>, <dfn>booleans</dfn>, <dfn>arrays</dfn>, <dfn>functions</dfn>, and <dfn>objects</dfn>.",
"Here's an example of a complex data structure:",
"<blockquote>var ourMusic = [<br> {<br> \"artist\": \"Daft Punk\",<br> \"title\": \"Homework\",<br> \"release_year\": 1997,<br> \"formats\": [ <br> \"CD\", <br> \"Cassette\", <br> \"LP\" ],<br> \"gold\": true<br> }<br>];</blockquote>",
"This is an array of objects and the object has various pieces of <dfn>metadata</dfn> about an album. It also has a nested <code>formats</code> array. Additional album records could be added to the top level array.",
"<strong>Note</strong><br>You will need a comma in between objects with more than one object in the array.",
"JavaScript Object Notation or <code>JSON</code> is a data interchange format used to store data (source: <a href=\"http://json.org/\">json.org</a>).",
"A property is the part of an object that associates a key (either a String value or a Symbol value) and a value (source: <a href=\"http://www.ecma-international.org/ecma-262/6.0/#sec-property\">ecma-international.org/ecma-262/6.0/#sec-property</a>). So, a property consists of a key - value pair. (source: <a href=\"http://spacetelescope.github.io/understanding-json-schema/reference/object.html#properties\">spacetelescope.github.io/understanding-json-schema/reference/object.html#properties</a>). Property keys (also known as names) should be in quotation marks.",
"Like JavaScript Objects, JSON is flexible because it is heterogeneous, meaning it permits <dfn>Data Structures</dfn> with arbitrary combinations of <dfn>strings</dfn>, <dfn>booleans</dfn>, <dfn>numbers</dfn>, <dfn>arrays</dfn>, and <dfn>objects</dfn>.",
"Here is an example of a JSON object:",
"<blockquote>var ourMusic = [<br> {<br> \"artist\": \"Daft Punk\",<br> \"title\": \"Homework\",<br> \"release_year\": 1997,<br> \"formats\": [ <br> \"CD\", <br> \"Cassette\", <br> \"LP\" ],<br> \"gold\": true<br> }<br>];</blockquote>",
"This is an array of objects and the object has various pieces of <dfn>metadata</dfn> about an album. It also has a nested <code>formats</code> array. Additional album records could be added to the top level array.",
"<strong>Note</strong><br>You will need to place a comma in between objects in JSON unless there is only one object in the array or containing object.",
"This is an array which contains one object inside. The object has various pieces of <dfn>metadata</dfn> about an album. It also has a nested <code>\"formats\"</code> array. If you want to add more album records, you can do this by adding records to the top level array.",
"Objects hold data in a property, which has a key-value format. In the example above, <code>\"artist\": \"Daft Punk\"</code> is a property that has a key of <code>\"artist\"</code> and a value of <code>\"Daft Punk\"</code>.",
