peek

function

Read a value from the scope without being observable.

`scope.peek(key [, options])`

Works just like get, but prevents any calls to add.

Walks up the scope to find a value at key. Stops at the first context where key has a value.

scope.peek("first.name");

Parameters

key {key}:
A dot seperated path. Use "." if you have a property name that includes a dot.

Returns

{*}:

The found value or undefined if no value is found.

Use

scope.peek(key) looks up a value in the current scope's context, if a value is not found, parent scope's context will be explored.

var list = [{name: "Justin"},{name: "Brian"}],
    justin = list[0];

var curScope = new Scope(list).add(justin);

curScope.peek("name"); //-> "Justin"
curScope.peek("length"); //-> 2
