The JavaScript string object allows us to play with the string of characters and it provides the means to manipulate the string object which is wrapped with a bunch of methods and Javascript primitive data type.

The syntax to create the string object is:

var theVal= new String(string);

Some of the string objects with there description are:

Constructor: The reference of the function will be returned which created the object

length: length of the string will be returned

prototype: The prototype property allows you to add properties and methods to an object.

Some methods:

charAt()

charCodeAt()

concat()

indexOf()

lastIndexOf()
