Tests

tests:
  - text: ''
    testString: 'assert(!getUserInput("index").match(/function/),"Traditional <code>function</code> expression was not used.");'
  - text: ''
    testString: 'assert(typeof bicycle.setGear === "function" && getUserInput("index").match(/setGear\s*\(.+\)\s*\{/), "<code>setGear</code> is a declarative function.");'
  - text: ''
    testString: 'assert((new bicycle.setGear(48)).gear === 48, "<code>bicycle.setGear(48)</code> changes the <code>gear</code> value to 48.");'

Challenge Seed

// change code below this line
const bicycle = {
  gear: 2,
  setGear: function(newGear) {
    "use strict";
    this.gear = newGear;
  }
};
// change code above this line
bicycle.setGear(3);
console.log(bicycle.gear);
