.push

localDataStorage.push( arrayKeyName, value [, value ...] )

This method stores value(s) under arrayKeyName, creating a new key if necessary, where the key prefix is prepended to arrayKeyName. As a shortcut for set, this can make a new key which is automatically an Array Key. This is also used to place a value onto an existing Array Key.

EXAMPLE:

● localData.push( 'nicknames', 'Mac', 'Will', 'Bill', 'Tom' )

🌐 This method may fire an event allowing you to monitor the key change.

✨ The complement to this is pull.

📝 NOTE: This method is specific to Array Keys and will fail if used on any other key type. Multiple values can be set only when making a new key. Pushing values onto an existing key must be done one at a time.
