[list].join
Category:Variables
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.
Examples
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 "));
Syntax
[list].join("separator")
Parameters
| Name | Type | Required? | Description |
|---|---|---|---|
| list | variable name | The variable name of the list (array) you want to join | |
| separator | string | The string to use to join the list (array). If none is given a comma will be used |

Tips
- If you use the newline character
"\n"as your separator you can create a list in which each element prints on a different line.
