Learn how to merge multiple arrays in JavaScript using the spread (...) operator.
You can merge any number of arrays by creating a new array and spreading existing arrays into the newly created array.
For example:
let friends = ["Megan", "Chris"]
let newFriends = ["Sarah", "Sam"]
let oldFriends = ["Sam", "Ryan"]
// to combine all of these into a single array
let allFriends = [...friends, ...newFriends, ...oldFriends]
Happy coding :)
