JavaScript concat method example
You can easily add two arrays to a single array with
the use of concat() method. This method uses the following syntax as
given below:
resultedArray = oneArray.concat ( secondArray,
thirdArray, ...);
The JavaScript array concat() method takes two
or more values and adds them to the end of array. Here in this example code we
have created two array object "firstArray" and "secondArray".
firstArray contains three elements and secondArray contains two
elements.
var firstArray = new Array(3);
firstArray[0]="Rose";
firstArray[1]="India";
firstArray[2]="Technologies";
var secondArray = new Array(2);
secondArray[0]="Private";
secondArray[1]="Limited";
Now we have concatenated these two arrays to produce
the final concatenated array finalArray which will be having five
elements. Here is the code of example :
<html>
<head>
<title>JavaScript array concat() example</title>
<script type="text/javascript">
var firstArray = new Array(3);
firstArray[0]="Rose";
firstArray[1]="India";
firstArray[2]="Technologies";
var secondArray = new Array(2);
secondArray[0]="Private";
secondArray[1]="Limited";
var finalArray = firstArray.concat(secondArray);
document.write("<b>First array is</b>=>"+firstArray+"<br> ");
document.write("<b>Second array is</b> =>"+secondArray+"<br> ");
document.write("<b>Concatenated array is</b> =>"+finalArray+"<br> ");
</script>
</head>
