+Truncates a string up to the nearest space before a specified length.
+

+- Calculates the nearest space before or at the strings set limit.
+- Appends a configurable ending (defaulting to `'...'`) to the truncated string.
+
+```js
+const truncateAtSpace = (string, characterLimit, ending = '...') => {
+  const lastSpace = string.slice(0, characterLimit + 1).lastIndexOf(' ');
+  return (string.length <= characterLimit) ? string : (lastSpace > 0) ? string.slice(0, lastSpace) + ending : ending;
+}
+```
+
+```js
+truncateAtSpace('This is a long excerpt that is far too long.', 25, '...'); // This is a long excerpt...
+```
