JavaScript to Concatenate Strings

To concatenate means to connect together. If you need to concatenate two or more strings, you can use the String object's concat method, as shown below.

<script type="text/javascript">
var firstString = "Now is the time for all good men ";
var secondString = "to come to the aid of their country.";

var myString = firstString.concat(secondString);
alert(myString);
</script>

In fact you can use the concat method to connect any number of strings together by separating the strings names with commas, using the syntax shown below.

string.concat(string1, string2, ... ,stringN)

In fact, using the concat method is not strictly necessary, as you can use the "+" operator to concatenate strings as shown below.

<script type="text/javascript">
var strFirst = "John";
var strLast = "Kennedy";
var strFull = strFirst + "F." + strLast;
alert(strFull);
</script>

You can use the "+" operator combined with the "=" operator to concatenate a character or string of characters to the end of an existing string as shown below.

<script type="text/javascript">
var strPatriot = "Now is the time for all good men ";
strPatriot += "to come to the aid of their country.";
alert(strPatriot);
</script>

Using this "+=" operator combination, you can concatenate groups of characters to create very long strings, as shown below.

<script type="text/javascript">
var strRabbit = "So Alice was considering, in her own mind, ";
strRabbit += "whether the pleasure of making a daisy-chain ";
strRabbit += "would be worth the trouble of getting up and ";
strRabbit += "picking the daisies, when suddenly a white ";
strRabbit += "rabbit with pink eyes ran close by her.";
alert(strRabbit);
</script>

As you can see, there are several ways to concatenate, or connect together, stings of characters.
