Remove the second last character of a string
javascript
Solution
This will truncate the last two characters of the string (and add a `]` back on):
str = str.substring(0, str.length - 2)+ ']';

Problem
How would I remove the second last character of a string using pure javascript. I can make it more specific by saying the last character of the string is ','. But there are other ',' present in the string. I just want the 2nd last one to be gone here is the string ``` var data = [{ "Store_ID": "46305", "inv list id": "jonesny-46305-inventory", "Store Address": "739 Reading Avenue Suite #306", "zip": "19610" }, { "Store_ID": "48760", "inv list id": "jonesny-46305-inventory", "Store Address": "1665 State Hill Rd", "zip": "19610" }, { "Store_ID": "48811", "inv list id": "jonesny-46305-inventory", "Store Address": "1665 State Hill Road", "zip": "19601" }, { "Store_ID": "53046", "inv list id": "jonesny-46305-inventory", "Store Address": "2630 Westview Dr", "zip": "19610" }, ] ``` Notice the last ',' the script which is producing it is this ``` var newVar = '['; for(var x in pdict.Stores){ newVar += '{' + '"Store_ID":"' + x.ID + '",'; newVar += '"inv list id":"' + x.inventoryList.ID + '",'; newVar += '"Store Address":"' + x.address1 + '",'; newVar += '"zip":"' + x.postalCode + '"},'; } newVar += ']'; ```
