Ohh yes we can define Constructor in Javascript and its very easy. 
Constructor is function, which we can defined as follow
<pre><code>function Cat(name){ 
 console.log('this',this);
 this.name=name;
 this.sleep=function(){
 console.log('sleep method has been called');
 },
 this.eat=function(){
 console.log('eat method has been called;');
 }
}

const myCat= new Cat('jeff');
</code></pre>Its Good practise to write first character capital of constructor name as above example I have written Cat.
as I have written 
<blockquote>
const myCat= new Cat(&#39;jeff&#39;);
</blockquote>
Here, new oprator will create empty object.
Then it will set all properties to this instance.
Finally it will return Cat object from this function, that&#39;s why we don&#39;t need to write return statement here.

Ohh yes we can define **Constructor** in Javascript and its very easy.

Its Good practise to write first character capital of constructor name as above example I have written **C**at.

Here, **new** oprator will create **empty object**.

Then it will set all properties to **this** instance.

Finally it will return Cat object from **this** function, that's why we don't need to write return statement here.
