Posting Code!
You may write comments in Markdown. This makes code easy to post, as you can write inline code like `<div>this</div>` or multiline blocks of code in triple backtick fences (```) with double new lines before and after.
Code of Conduct
Absolutely anyone is welcome to submit a comment here. But not all comments will be posted. Think of it like writing a letter to the editor. All submitted comments will be read, but not all published. Published comments will be on-topic, helpful, and further the discussion or debate.

There’s a way shorter way :-)
Or, you could use slice();
var origString = ‘Happy Dance7’;
var trimmedString = origString.slice(0,-1);
console.log(trimmedString);
Shorter code is better. Thanks to jQuery.
‘slice’ isn’t jQuery
