--description--

ES6 adds some nice support for easily defining object literals.

Consider the following code:

const getMousePosition = (x, y) => ({
  x: x,
  y: y
});

getMousePosition is a simple function that returns an object containing two properties. ES6 provides the syntactic sugar to eliminate the redundancy of having to write x: x. You can simply write x once, and it will be converted tox: x (or something equivalent) under the hood. Here is the same function from above rewritten to use this new syntax:

const getMousePosition = (x, y) => ({ x, y });

--instructions--

Use object property shorthand with object literals to create and return an object with name, age and gender properties.

--hints--

createPerson("Zodiac Hasbro", 56, "male") should return {name: "Zodiac Hasbro", age: 56, gender: "male"}.

assert.deepEqual(
  { name: 'Zodiac Hasbro', age: 56, gender: 'male' },
  createPerson('Zodiac Hasbro', 56, 'male')
);

Your code should not use key:value.

(getUserInput) => assert(!getUserInput('index').match(/:/g));

--seed-contents--

const createPerson = (name, age, gender) => {
  // Only change code below this line
  return {
    name: name,
    age: age,
    gender: gender
  };
  // Only change code above this line
};

--solutions--

const createPerson = (name, age, gender) => {
  return {
    name,
    age,
    gender
  };
};
