Returns the array as a string with elements joined by an optional separator
Sometimes we want to put all of the items in our lists together. join allows us to do this and to choose what we want in between each of the items. The separator we choose will be placed between every single item in the resulting string.
Example: Simple Join Join a list of strings with the word "and"
var colors = ["red","orange","yellow","green","blue"];
console.log("My favorite colors are " + colors.join(" and "));
Example: Multiline-String Join a string so that each element prints on another line.
var colors = ["red","orange","yellow","green","blue"]; console.log("My favorite colors are:\n" + colors.join(" \n "));
[list].join(separator)
