    <h1>What are objects</h1>
    <p>Objects are a data type. JavaScript follows an 'object based paradigm'. Which means in JS an object is a stand-alone entity (object) with properties. Properties come in key: value pairs. They are like variables. In the sense that variables reference some value in memory. The same way, in objects the property key: value pairs are akin to variables.</p>

     <div class="col-sm-6">
    <h1>Why?</h1>
       <p>Think about it... In the real world most things are "objects". For example your car, the food you eat, the bed you sleep on etc. So the objects in your real life have <span class="special">properties</span> (example red car, thin mattress) and there is some <span class="special">functionality</span> associated with the objects. The car has "driving" functionality and the "mattress" has the "sleep" functionality.</p>
       <p>Isn't the whole point of JS to mimic real life stuff (objects) so that you can make apps example <b>Uber</b></p>

         <h1>Properties</h1>
         <p>Just like real life objects have characteristics example a "red" car. The same way in JavaScript we can create objects that have certain characteristics. Except in JS these are called "properties" and not characteristics.</p>
 <p>Objects have properties. A property is a "key" : "value" pair. This association may be familiar to you from attributes and values in HTML. Example  a div class="myDiv". The values can be of any data type example strings, numbers, booleans, an array.</p>
  <p> Example:</p>
    <p> name: "Rocko"</p>
       </div> <!-- end of col-sm-6 -->
        <div class="col-sm-6">
          <h1>Method</h1>
          <p>A method refers to a function of an object. It is a the value of a property in an object. Think of a method as an "action" of an object. Example the method/action of a car object is driving.</p>
          <p>Example:</p>
          like: function(){
          console.log("I love treaties!")
          }
