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 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 });
Use simple fields with object literals to create and return a Person object.
