mw.Map

Collection of values by string keys.

This is an internal class that backs the mw.config and mw.messages APIs.

It allows reading and writing to the collection via public methods, and allows batch iteraction for all its methods.

For mw.config, scripts sometimes choose to "import" a set of keys locally, like so:

var conf = mw.config.get( [ 'wgServerName', 'wgUserName', 'wgPageName' ] );
conf.wgServerName; // "example.org"

Check the existence ("AND" condition) of multiple keys:

if ( mw.config.exists( [ 'wgFoo', 'wgBar' ] ) );

For mw.messages, the mw.Map#set method allows mw.loader and mw.Api to essentially extend the object, and batch-apply all their loaded values in one go:

mw.messages.set( { "mon": "Monday", "tue": "Tuesday" } );
