let userName = { name: "John Doe" };
let userSex = { sex: "Male" };

let user = { ...userName, ...userSex };

console.log(user); // { name: "John Doe", sex: "Male" }

// Note: In a situation where one key has another property,
// the last property overrides the first instance:

let userName = { name: "John Doe" };
let userSex = { sex: "Female", name: "Jane Doe" };

let user = { ...userName, ...userSex }; // { name: "Jane Doe", sex: "Female" }

How to Concatenate or Merge Arrays With the Spread Operator in JavaScript

Comment

let femaleNames = ["Daniel", "Peter", "Joe"];
let maleNames = ["Sandra", "Lucy", "Jane"];

let allNames = [...femaleNames, ...maleNames];

console.log(allNames); // ["Daniel","Peter","Joe","Sandra","Lucy","Jane"]

// It's also important to know that we can use the same approach for as many arrays
// as we have. We can also add individual elements within the array:

let femaleNames = ["Daniel", "Peter", "Joe"];
let maleNames = ["Sandra", "Lucy", "Jane"];
let otherNames = ["Bill", "Jill"];

let moreNames = [...otherNames, ...femaleNames, ...maleNames];
let names = [...moreNames, "Ben", "Fred"];


// This saves us the stress of using a complicated syntax like the concat() method
