+# --description--
+
+In this lab you will build a function that check if a value is classified as a boolean primitive.
+
+Boolean primitives are `true` and `false`.
+
+**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should have a function called `booWho` that receives one argument.
+1. If the argument received is a boolean primitive, the function should return `true`.
+1. If the argument is any other value, the function should return `false`.
+
+# --hints--
+
+You should have a `booWho` function.
+
+```js
+assert.isFunction(booWho);
+```
+
+`booWho(true)` should return `true`.
+
+```js
+assert.isTrue(booWho(true));
+```
+
+`booWho(false)` should return `true`.
+
+```js
+assert.isTrue(booWho(false));
+```
+
+`booWho([1, 2, 3])` should return `false`.
+
+```js
+assert.isFalse(booWho([1, 2, 3]));
+```
+
+`booWho([].slice)` should return `false`.
+
+```js
+assert.isFalse(booWho([].slice));
+```
+
+`booWho({ "a": 1 })` should return `false`.
+
+```js
+assert.isFalse(booWho({ a: 1 }));
+```
+
+`booWho(1)` should return `false`.
+
+```js
+assert.isFalse(booWho(1));
+```
+
+`booWho(NaN)` should return `false`.
+
+```js
+assert.isFalse(booWho(NaN));
+```
+
+`booWho("a")` should return `false`.
+
+```js
+assert.isFalse(booWho('a'));
+```
+
+`booWho("true")` should return `false`.
+
+```js
+assert.isFalse(booWho('true'));
+```
+
+`booWho("false")` should return `false`.
+
+```js
+assert.isFalse(booWho('false'));
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+function booWho(bool) {
+  return typeof bool === 'boolean';
+}
+
+```
