Use it when: You want to translate/map all elements in an array to another set of values.
Example: convert Fahrenheit temps to Celsius.
var fahrenheit = [0, 32, 45, 50, 75, 80, 99, 120];
var celcius = fahrenheit.map(function(elem) {
-- Remove the history from | |
rm -rf .git | |
-- recreate the repos from the current content only | |

git add . | |
git commit -m "Initial commit" | |
-- push to the github remote repos ensuring you overwrite history | |
git remote add origin [email protected]:<YOUR ACCOUNT>/<YOUR REPOS>.git |
There is no way to store an empty object/array/null value. | |
There are also no actual arrays. Array values get stored as objects with integer keys. | |
(If all keys are integers, it will be returned as an array.) | |
Basically, it's one giant tree of hashes with string keys. | |
Simply write a value to any location, and the intermediary locations will automatically come into existance. | |

DataSnapshot : Container for a subtree of data at a particular location. |
Generally, you will add a git remote for your Heroku app during the Heroku app creation process, i.e. heroku create
. However, if you are working on an existing app and want to add git remotes to enable manual deploys, the following commands may be useful.
Note that on Heroku, you must always use master
as the destination branch on the remote. If you want to deploy a different branch, you can use the syntax local_branch:destination_branch
seen below (in this example, we push the local staging
branch to the master
branch on heroku.
$ git remote add staging https://git.heroku.com/staging-app.git
