JavaScript array merge
In this Tutorial we want to describe you a code that help you in
understanding how to merge two different array into one array using Java Script.
We declare a array variable that is used to store array object. An array component
is accessed by an array expression that consists of an expression whose value is
an array reference indicated by subscripts indexing expression enclosed by [].
An array with size length of x can be indexed by the integers from 0
to x-1.The document. write prints the elements in an array. The
for loop execute the script till the array variable is less than array length.The
document. write print the list of element in an array. In the same way we
declare another array variable array1 that is used to used to store an array
object and each array reference hold the list of element in array1 variable
indicated by the indexes. The document.write print the list of element in array.
On clicking a button the function1( )is invoked that include
1)array.concat(array1) - concatenated the two array and store in a variable c
Finally the document. write print the concatenated array by merging two
array.

document.write(array1[j]+"<br>")
}
document.write("<br />");
