Instructions

Tests

tests:
  - text: <code>booWho(true)</code> debe devolver true.
    testString: 'assert.strictEqual(booWho(true), true, "<code>booWho(true)</code> should return true.");'
  - text: <code>booWho(false)</code> debe devolver verdadero.
    testString: 'assert.strictEqual(booWho(false), true, "<code>booWho(false)</code> should return true.");'
  - text: ' <code>booWho([1, 2, 3])</code> debe devolver falso.'
    testString: 'assert.strictEqual(booWho([1, 2, 3]), false, "<code>booWho([1, 2, 3])</code> should return false.");'
  - text: ' <code>booWho([].slice)</code> debe devolver falso.'
    testString: 'assert.strictEqual(booWho([].slice), false, "<code>booWho([].slice)</code> should return false.");'
  - text: ' <code>booWho({ &quot;a&quot;: 1 })</code> debe devolver falso.'
    testString: 'assert.strictEqual(booWho({ "a": 1 }), false, "<code>booWho({ "a": 1 })</code> should return false.");'
  - text: <code>booWho(1)</code> debe devolver falso.
    testString: 'assert.strictEqual(booWho(1), false, "<code>booWho(1)</code> should return false.");'
  - text: <code>booWho(NaN)</code> debe devolver falso.
    testString: 'assert.strictEqual(booWho(NaN), false, "<code>booWho(NaN)</code> should return false.");'
  - text: <code>booWho(&quot;a&quot;)</code> debe devolver falso.
    testString: 'assert.strictEqual(booWho("a"), false, "<code>booWho("a")</code> should return false.");'
  - text: <code>booWho(&quot;true&quot;)</code> debería devolver falso.
    testString: 'assert.strictEqual(booWho("true"), false, "<code>booWho("true")</code> should return false.");'
  - text: <code>booWho(&quot;false&quot;)</code> debe devolver false.
    testString: 'assert.strictEqual(booWho("false"), false, "<code>booWho("false")</code> should return false.");'

Challenge Seed

function booWho(bool) {
  // What is the new fad diet for ghost developers? The Boolean.
  return bool;
}

booWho(null);

Solution

function booWho(bool) {
  return typeof bool === "boolean";
}

booWho(null);
