+console.time polyfill
+=====================
+
+Lightweight and simple polyfill for `console.time()` and `console.timeEnd()`
+
+## Example usage:
+
+```
+# Start the timer by passing it a key
+console.time('myTimer');
+
+# Call timeEnd later to see how long an operation took
+setTimeout(function() {
+  console.timeEnd('myTimer');
+}, 2000);
+
+# It should then log out something like like..
+# myTimer: 2000ms
+```
+
+For more information on `console.time()` visit [MDN] (https://developer.mozilla.org/en-US/docs/Web/API/console.time).
