what is the meaning of word this near the property in JavaScript
<p>Hello I'm a newcomerin JavaScript language.
I started to see some examples of JavaScript code.</p>

<p>and i cant understand the following code segment:</p>

<pre><code>function Employee(name,salary)
 {
  this.name=name;
  this.salary=salary;

  this.paycheck=function()
  {
   var monthly=this.salary/12;
   document.write(this.name+ ": " +monthly);
  };
} 
var emp= new Employee("Fred",10000);
emp.paycheck();
</code></pre>

<p>My question: what is the meaning of word <strong>this</strong> near the property inside class  (i.e.  ,this.name=name; this.salary=salary; )?</p>

<p>Thank you in advance!</p>
