String is a Data Type that is used to store storing and manipulating text.

Strings are written inside Double Quotes or Single Quotes.

Example :

"hello" , "Hey There" , "Any Text" , "123", "World123"

Any Thing you write inside Double Quotes is considered to be a Text by Javascript.

Declaring String


var variableName = "Any Text";

You can use Double Quotes or Single Quotes, Both Will Work.


var helloText = "Hey There! Welcome To My World"; var newHelloText = 'How Are You???'; console.log(helloText); console.log(newHelloText); // Output // Hey There! Welcome To My World // How Are You???

Escape Character

As you all know, Strings are written inside the Double quotes or Single Quotes. So, when you will try to enter a word inside double quotes then javascript will misunderstand it and thus will not give desired output

For Example :

var string1 = "Hey There!!! "We are Top Of The World"; console.log(string1); //Output ** This Program Will Not Be Executed **

Correct Program

var string1 = "Hey There!!! \"We are Top Of The World\""; console.log(string1); // Output // Hey There!!! "We are Top Of The World"

To Achieve Desired Output You have to use Backslash (\\)

Here We have list of Escape Characters. These are also used for Giving Special Functionality Like New Line or Vertical Space.
