API

new Scope()

Creates a new instance of the scope. Doesn't take any arguments so do what you will.

Scope#push(scope)

Adds an object for use in the lookup. Objects added later will be searched first.

• scope A value for use in the lookup process. If the value isn't an object or array, it'll be skipped over.

Returns the scope instance for chaining.

Scope#pop()

Removes one level from the scope chain. If the chain is empty, there is no effect.

Returns the scope instance for chaining

Scope#get(key)

Looks up a key within the scope chain and returns the value of the first one found. If nothing is found, it returns undefined. If the key is an empty string, it returns the last known scope (In case you wanted a way to reference the last scope in the chain by value).

• key The key to look up

Returns the value found or undefined

Scope#peek()

Returns the last object pushed into the scope chain. If the chain is empty, returns undefined

Returns The last object in the scope chain or undefined

Scope#all()

Returns the list of objects in the scope chain. This is a copy of the list so it's OK to mutate it as long as you don't mutate the actual values in the objects.

Returns the list of objects in the scope chain.
