Remove array object by value

JavaScript
13

Got it! Error coded in in case no numbers are at the end of the URL (so e.g. the error message is for if this URL comes through):

https://www.juicer.io/api/feeds/320738?filter=

Last thing I need to do is somehow sort my sourceData array to match the order of my filters in my function call. Working on that now:

requestPostData(endpoint, feedOptions, callback) {
    var filters = Object.entries(this.filters);
    var matches = endpoint.match(/filter=([\d,]+)/);
    var nums = matches == null ? [] : matches[1].split(",").filter((x) => x); 
    var output = {};
    var sourceData = {};
    var sourceNumbers = Object.entries(endpoint.split("?filter=").pop().split(","));
    var urls = sourceNumbers.map(filter => endpoint.split("?")[0] + "?filter=" + filter[1]);
    if(sourceNumbers[0][1] === "") {
      console.error("Error: Please select sources in the element");
      return;
    }
    Promise.all(urls.map(url =>
      fetch(url).then(resp => resp.json())
    )).then(values => {
      values.forEach(function(value, index) {
        if(value.posts.items[0].source.source.toLowerCase() in sourceData) {
          sourceData[value.posts.items[0].source.source.toLowerCase()] = sourceData[value.posts.items[0].source.source.toLowerCase()] + "," + urls[index].split("?filter=")[1];
        } else {
          sourceData[value.posts.items[0].source.source.toLowerCase()] = endpoint.split("?filter")[0] + "?filter=" + urls[index].split("?filter=")[1];
        }
      });
      filters.forEach((x) => {
        if(sourceData[x[0]] === undefined) {
          sourceData[x[0]] = endpoint.split("?filter")[0] + "?filter="+x[0] + "&per=" + x[1] + "&page=" + this.options.feed.page;
        } else {
          sourceData[x[0]] = sourceData[x[0]] + "&per=" + x[1] + "&page=" + this.options.feed.page;
        }
      });
      console.log(Object.values(sourceData));
      Promise.all(Object.values(sourceData).map(url =>
        fetch(url).then(resp => resp.json())
      )).then(callback);
    });
  }

Codepen above has been updated to show it working.
