How to Concatenate Join and Sort Array in JavaScript
How to Concatenate Join and Sort Array in JavaScript
In the previous post, I have already described about "How to Loop Through JavaScript Array". Along with accessing an element of an array using looping statements, you can also concatenate, join and sort an array in JavaScript. In this post you will learn about How to Concatenate, Join and Sort Array in JavaScript.
How to Join Two Arrays using Concat()
Using concat() method, you can join to arrays array1 and array2 as below.
var array1=new Array(3);
array1[0]="Saab"
array1[1]="Volvo"
array1[2]="BMW"
var array2=new Array(3);
array2[0]="Yamaha"
array2[1]="Honda"
array2[2]="Bajaj"
var array3=array1.concat(array2);
for(i=0; i<array3.length;i++)
{
document.write(array3[i]+"<br/>")
}
</script>
Preview:
Here the method array1.concat(array2) concentrates two arrays array1 and array2.
How to Put Array Elements Into a String using Join()
You can use the join() method to put all the elements of an array into a string as the following script.
<script>
var array1=new Array(3);
array1[0]="Yamaha"
array1[1]="Honda"
array1[2]="Bajaj"
document.write(array1.join()+"<br/>");
document.write (array1.join("."));
</script>
