Tests

tests:
  - text: ''
    testString: 'assert(increment(5, 2) === 7, "The result of <code>increment(5, 2)</code> should be <code>7</code>.");'
  - text: ''
    testString: 'assert(increment(5) === 6, "The result of <code>increment(5)</code> should be <code>6</code>.");'

Challenge Seed

const increment = (function() {
  "use strict";
  return function increment(number, value) {
    return number + value;
  };
})();
console.log(increment(5, 2)); // returns 7
console.log(increment(5)); // returns 6
