merge aray using spread and set code example

Example: combining two arrays using spread syntax

////////////////////////////////////////////////////////////////////
////// SPREAD SYNTAX ///// Dead Milkmen Lyrics "Punk Rock Girl" ////
// combining two arrays and multiple items using spread syntax 
// Javascript [...spreadSyntax,] lets you pull out or ("spread")
// a copy of what's inside the array or object 
// it can also be used to create a new array or object 

// EXAMPLE: [...combining, ...twoArrays] 
// hit alt / command j or option / command j

// array 1 type 
const firstArray = ["just", "you", "and", "me"];
// array 2 type
const secondArray = ["punk", "rock", "girl"];

// (hit return) to store the arrays  
// combine them into a new array using a syntax 
// [...arrayName, ...arrayName];

const newArray = [...firstArray, ...secondArray]; 
// (hit return) The items get spread out 
// then combined together 
// call your third Array then (hit return)

newArray 
// answer
(7) ["just", "you", "and", "me", "punk", "rock", "girl"]

// This could also be done with an array and an "added string"
const sillyString = ["We'll dress like Minnie Pearl ", ...newArray]; 
// (hit return) then call sillyString 

sillyString
// (hit return) answer should be 
(8) ["We'll dress like Minnie Pearl ", "just", "you", "and", "me", "punk", "rock", "girl"]

// You can spread and combine all 
// sorts of silly data that you
// normally store in an array 
// add another string for fun 

const longString = ["And security guards trailed us to a record shop We asked for Mojo Nixon They said he don't work here We said if you don't got Mojo Nixon then your store could use some fixin"];

const moreStuff = [...sillyString, "We went", 2, "a shopping mall", "and", { someProperty: "laughed at all the shoppers" }, ...longString];

// RESULT  
// call moreStuff

moreStuff
