Introduction

First, let’s understand what an array is. An array is a data structure used to manage multiple pieces of data within a single variable.
For example, you can store different characters in an array.

In this example, we will use the following two arrays:

onearry = [ "A", "B", "C", "D" ]
twoarry = [ "e", "f", "g", "h", "i", "k" ]

Now, let’s see how to merge these arrays into a new array.

How to Merge Arrays Using jQuery’s merge Function

jQuery provides a built-in function called merge that makes merging arrays very simple.
Here is a sample code using the merge function to combine two arrays:

<script src="./jquery-2.2.0.min.js"></script>

<script type="text/javascript">
$(function() {
  var onearry = [ "A", "B", "C", "D" ];
  var twoarry = [ "e", "f", "g", "h", "i", "k" ];
  var mrgarry = $.merge( $.merge( [], onearry ), twoarry );

  var mrglist = '';
  for (var i=0; i<mrgarry.length;i++){
    mrglist += '<li>'+ mrgarry[i] + '</li>';
  }

  document.getElementById('mrglist').innerHTML = mrglist;
});
</script>

In this code, we use the merge function to merge onearry and twoarry into a new array called mrgarry.
Then, we loop through the merged array and display its elements as a list inside the HTML element with id="mrglist".

Preparing HTML and CSS

To display the merged result, we need to set up HTML and CSS properly.

HTML Code

In HTML, we create a section where the merged result will be displayed.
The id="mrglist" tag will output the merged result.

<h1>Merging Two Arrays and Displaying the Output</h1>

<p>
Array 1: onearry = [ "A", "B", "C", "D" ]<br>
and<br>
Array 2: twoarry = [ "e", "f", "g", "h", "i", "k" ]<br>
will be merged and displayed below.
</p>

<ul id="mrglist"></ul>

CSS Code

The CSS below styles the displayed list.

<style type="text/css">
body{
  font-family:Verdana,"Hiragino Kaku Gothic Pro","ヒラギノ角ゴ Pro W6",Osaka,"ＭＳ Ｐゴシック",Arial,sans-serif;
  padding: 0;
  margin: 0;
  line-height: 1.8em;
}
h1{
  font-size:16px;
  text-align:center;
  font-weight:normal;
  padding:10px 0;
  position: relative;
}
p{
  text-align: center;
  padding-bottom: 20px;
}
#mrglist{
  width: 20px;
  margin: 0 auto;
}
ul{
  list-style: none;
}
</style>
