How to use String concat() to add two strings together

Description

concat() concatenates one or more strings to another and returns the concatenated string.

Example


var stringValue = "hello "; 
var result = stringValue.concat("world"); 
console.log(result); //"hello world" 
console.log(stringValue); //"hello" 
/*from  w ww .j ava  2 s  . c o m*/

The code above generates the following result.

Example 2

The concat() method accepts any number of arguments:


var stringValue = "hello "; 
var result = stringValue.concat("world", "!"); 
        //from w  w w .j a  va  2  s. c o m
console.log(result); //"hello world!" 
console.log(stringValue); //"hello"
