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

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)

You should look at charAt function and take length of the string.

var b = 'I am a JavaScript hacker.';
console.log(b.charAt(b.length-1));

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.

Lots of String functions explained here

Use the charAt method. This function accepts one argument: The index of the character.

var lastCHar = myString.charAt(myString.length-1);

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

here is a simple fiddle

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);

myString.substring(str.length,str.length-1)

You should be able to do something like the above - which will get the last character
