ES6 Write Concise Object Literal Declarations Using Simple Fields
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 to x: 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 });
Task
Use simple fields with object literals to create and return a Person object.
const createPerson = (name, age, gender) => {
"use strict";
// change code below this line
return {
name: name,
age: age,
gender: gender
};
// change code above this line
};
console.log(createPerson("Zodiac Hasbro", 56, "male")); // returns a proper object
Task Conditions to be satisfied
- the output is {name: “Zodiac Hasbro”, age: 56, gender: “male”}.
- No : were used.
Solution
const createPerson = (name, age, gender) => {
"use strict";
// change code below this line
name, age, gender;
// change code above this line
};
console.log(createPerson("Zodiac Hasbro", 56, "male")); // returns a proper object
