Checking value from array javascript


I found usefull following URL working with Javascript Array.
http://www.javascriptkit.com/jsref/arrays.shtml

Here is my code to check value from array

var MyArrayVar = new Array(1, 2, 3, 4, 5);

testVar = 2;

if(MyArrayVar.indexOf(testVar) >= 0) {
alert(“We got testVar in MyArrayVar”);
}else{
alert(“We did not got testVar in MyArrayVar”);
}

As per this condition I am chekcing the What is returned by this MyArrayVar.indexOf(testVar).
You can check this by using “alert(MyArrayVar.indexOf(testVar));” line.
You will get this number value if testVar number or value present in Array.

You that value is not present in Array you will get the -1 result always.
