Array object is used to store multiple values in a single variable. In JavaScript, am array can hold different data types in a single array slot. An array can be constructed in the following ways:
- Using the array constructor.
- Using the array literal notation.
Using the array constructor:
An empty array is constructed in case when you do not know the exact number of elements to be inserted in the array.
Syntax:
- varmyArray=new array();
- varmyArray=new array(size);
Array literal notations are comma-separated list of items enclosed by square brackets.
Syntax:
- varmyArray=[“element 1”,”element 2”];
- varmyArray=[6,true,false,true];
- Create a document called ArrayFunctions.html.
- Write the following code:
- <!DOCTYPE HTML>
-
- <HEAD>
- <TITLE>Array Functions</TITLE>
- </HEAD>
-
- <BODY>
- <SCRIPT type="text/javascript">
- myarray1 = new Array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday");
- myarray2 = new Array(1, 2, 3, 4, 5);
- document.write("Array 1: " + myarray1 + "<br>");
- document.write("Array 2: " + myarray2 + "<br>");
- document.write("Concatenated arrays: " + myarray1.concat(myarray2) + "<br>");
- document.write("Joined two arrays: " + myarray1.join(myarray2) + "<br>");
- document.write("Array 1 pop out: " + myarray1.pop() + "<br>");
- document.write("Reversed array 1: " + myarray1.reverse() + "<br>");
- document.write("Shifted array 1: " + myarray1.shift() + "<br>");
- document.write("Sorted array 1: " + myarray1.sort() + "<br>");
- document.write("Array 2 in string format: " + myarray2.toString() + "<br>");
- </SCRIPT>
- </BODY>
-
- </HTML>
