String Type

Description

The String type is the object representation for strings and is created using the String constructor as follows:

var stringObject = new String("hello world");

The methods of a String object are available on all string primitives.

valueOf(), toLocaleString(), and toString() from String type return the object's primitive string value.

Example


var stringValue = "hello world";
console.log(stringValue.toString());
console.log(stringValue.valueOf());
console.log(stringValue.toLocaleString());

The code above generates the following result.

Length

Each instance of String contains a property, length, which indicates the number of characters in the string. Consider the following example:


var stringValue = "hello world";
console.log(stringValue.length);   //"11"

The code above generates the following result.
