JavaScript is an Object Oriented Programming (OOP) language.
An OOP language allows you to define your own objects and make your own variable types.
Object Oriented Programming
JavaScript is an object oriented language. However, in practice objects defined by the programmer himself are rarely used, except in complex DOM API's. Of course such standard objects as window and document and their numerous offspring are very important, but they are defined by the browser, not by the programmer.
Methods and properties
In JavaScript you can define your own objects. In addition, you can assign methods and properties to each object, pre-written or self-defined.
Methods
Methods are 'things that do something', they can be recognized by their brackets (). When you call them, like object.method(), something happens.
<script type="text/javascript">
var str="vyom"
document.write(str.toUpperCase())
</script>
Output
VYOM
properties
A JavaScript object has properties associated with it. You access the properties of an object with a simple notation:
Example:
Here it Show the property of length of the text.
<script type="text/javascript">
var text="vyom"
document.write(text.length)
</script>
Output
4
