I am using IFTTT to post to Facebook page from pinterest RSS. Here is the url of RSS Feed - Link
What I want to do is replace all 236x string with 564x in the RSS feed result. As I am not a programmer I wrote this code to replace 236x with 564x in Javascript .
var url=Feed.newFeedItem.EntryImageUrl;
var newurl=url.replace(/236x/g,'564x');
But it seems it is not working can any one help me with proper filter code for IFTTT in Javascript , TypeScript. Thanks in advance.
