How can I get the last character in a string? [duplicate]

If I have the following variable in javascript

 var myString = "Test3";

what is the fastest way to parse out the "3" from this string that works in all browsers (back to IE6)

Solution 1:

Since in Javascript a string is a char array, you can access the last character by the length of the string.

var lastChar = myString[myString.length -1];

Solution 2:

It does it:

myString.substr(-1);

This returns a substring of myString starting at one character from the end: the last character.

This also works:

myString.charAt(myString.length-1);

And this too:

myString.slice(-1);

Solution 3:

 var myString = "Test3";
 alert(myString[myString.length-1])

here is a simple fiddle

Solution 4:

Javascript strings have a length property that will tell you the length of the string.

Then all you have to do is use the substr() function to get the last character:

var myString = "Test3";
var lastChar = myString.substr(myString.length - 1);

edit: yes, or use the array notation as the other posts before me have done.
