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