freeCodeCamp Challenge Guide: Use the Triple Equals to Assert Strict Equality

Use the Triple Equals to Assert Strict Equality


Problem Explanation

To begin, locate the file “tests/1_unit_tests.js” and scroll to the suite of tests for ‘Equality’.

This file contains multiple suites of tests for the project, and this challenge requires you to make the tests in /** 6 */ pass.


Hints

Hint 1

The lines in the test should be changed from assert.fail() to either assert.strictEqual() or assert.notStrictEqual().


Solutions

Solution 1 (Click to Show/Hide)
/** 6 - .strictEqual(), .notStrictEqual() **/
// .strictEqual() compares objects using '==='
test('#strictEqual, #notStrictEqual', function() {
  assert.notStrictEqual(6, '6');
  assert.strictEqual(6, 3 * 2);
  assert.strictEqual(6 * '2', 12);
  assert.notStrictEqual([1, 'a', {}], [1, 'a', {}]);
});
