 A variable is a name that can reference a specific value. Variables are  declared using var followed by the variable's name.


  Here's an example:


     var example;



  The above variable is declared, but it isn't defined (it does not yet  reference a specific value).


  Here's an example of defining a variable, making it reference a specific  value:


     var example = 'some string';


 # NOTE


  A variable is declared using var and uses the equals sign to define the
  value that it references. This is colloquially known as "Making a variable
  equal a value".
