It sounds like you're looking for length property:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/length

 

If you're unsure how to use length, there are many resources here:

For future reference, JavaScript questions should be posted in the JavaScript forum:
