I've got a piece of javascript that dynamically calls an image URL

if (searchResult['image'] != undefined) {
                    if (searchResult['link'] != undefined) {
                        searchResultNode += '<a class="image" href="' + searchResult['link'] + '">';
                    }

                    searchResultNode += '<img src="' + searchResult['image'] + '" class="ss360-search-result-image" />';

                    if (searchResult['link'] != undefined) {
                        searchResultNode += '</a>';
                    }

                }

What function can I write to edit the img src URL so that it removes the file name suffix (.png, .jpg, .jpeg), adds '-764x375' to the URL, and then readds the filename suffix?

    If you can always rely on there being a suffix, you could replace every occurrence of e.g. .jpg by -764x375.jpg if it occurs at the end of the string. See e.g. stackoverflow.com/questions/2729666/… Commented Mar 11, 2017 at 14:38
  • You can split the string at the last index of . to getan array and you know what to do next. Commented Mar 11, 2017 at 14:42
