+# --description--
+
+Write a program to find the [mode](https://en.wikipedia.org/wiki/Mode (statistics) "wp: Mode (statistics)") value of a collection.
+
+The case where the collection is empty may be ignored. Care must be taken to handle the case where the mode is non-unique.
+
+If it is not appropriate or possible to support a general collection, use a vector (array), if possible. If it is not appropriate or possible to support an unspecified value type, use integers.
+
+# --hints--
+
+`mode` should be a function.
+
+```js
+assert(typeof mode === 'function');
+```
+
+`mode([1, 3, 6, 6, 6, 6, 7, 7, 12, 12, 17])` should equal `[6]`
+
+```js
+assert.deepEqual(mode(arr1), [6]);
+```
+
+`mode([1, 2, 4, 4, 1])` should equal `[1, 4]`.
+
+```js
+assert.deepEqual(mode(arr2).sort(), [1, 4]);
+```
+
+# --seed--
+
+## --after-user-code--
+
+```js
+const arr1 = [1, 3, 6, 6, 6, 6, 7, 7, 12, 12, 17];
+const arr2 = [1, 2, 4, 4, 1];
+```
+
+## --seed-contents--
+
+```js
+function mode(arr) {
+
+  return true;
+}
+```
+
+# --solutions--
+
+```js
+function mode(arr) {
+  const counter = {};
+  let result = [];
+  let max = 0;
+  // for (const i in arr) {
+  arr.forEach(el => {
+    if (!(el in counter)) {
+      counter[el] = 0;
+    }
+    counter[el]++;
+
+    if (counter[el] === max) {
+      result.push(el);
+    }
+    else if (counter[el] > max) {
+      max = counter[el];
+      result = [el];
+    }
+  });
+  return result;
+}
