What's wrong with my regex replace functions?

Question

    var storeName = "St. Bob's Store";
    var storeId = storeName.replace(/./g,"").replace(/\s/g, '').replace(/'/g,"")
    $('#storeName').html(storeName)
    $('#storeId').html("(" + storeId + ")")
    
    console.log("Updating " + storeName + "(" + storeId + ")");

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="storeName">Loading</div>
<div id="storeId">loading</div>

What am I doing wrong with storeId? It's empty.

If your intent is to replace the dot in storeName, you need to escape it in the regex. A dot means "any single character". — ghoti

Keep in mind that expert's exchange != expert sex change. Same storeId though! — James

If you want to match "dot" char, you have to escape it, like this:

var storeId = storeName.replace(/\./g,"").replace(/\s/g, '').replace(/'/g,"");

Here's a fiddle: https://jsfiddle.net/e63bq01L/

If not escaped, the dot matches all characters in a string.

You have to escape the dot character:

storeName.replace(/\./g,"").replace(/\s/g, '').replace(/'/g,"")

Otherwise, you will replace everything.
