Description
const getMousePosition = (x, y) => ({
x: x,
y: y
});
getMousePosition
is a simple function that returns an object containing two fields.
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
Person
object.
Tests

- text: 'the output is <code>{name: "Zodiac Hasbro", age: 56, gender: "male"}</code>.'
testString: 'assert(() => {const res={name:"Zodiac Hasbro",age:56,gender:"male"}; const person=createPerson("Zodiac Hasbro", 56, "male"); return Object.keys(person).every(k => person[k] === res[k]);}, "the output is <code>{name: "Zodiac Hasbro", age: 56, gender: "male"}</code>.");'
- text: 'No <code>:</code> were used.'
testString: 'getUserInput => assert(!getUserInput("index").match(/:/g), "No <code>:</code> were used.");'
