#### store.forEachTiddler(callback) #### store.forEachTiddler([sortField,[excludeTag,]]callback)
Invokes a callback for each tiddler in the store. The callback is called with the title of the tiddler and a reference to the tiddler itself. For example: Invokes a callback for each tiddler in the store, optionally sorting by a specified field and excluding tiddlers with a specified tag. The callback is called with the title of the tiddler and a reference to the tiddler itself. For example:
store.forEachTiddler(function(title,tiddler) { store.forEachTiddler(function(title,tiddler) {
console.log(title); console.log(title);
