An Angular scope is a JavaScript object with additional APIs useful for watching property changes, Angular scope is the model in Model-View-Controller paradigm. Instances of scope serve as the context within which all expressions get evaluated.
You can think of Angular scope objects as the medium through which the model, view, and controller communicate. Scopes are linked during the compilation process with the view. This linkage provides the contexts in which Angular creates data-bindings between the model and the view.
In addition to providing the context in which data is evaluated, Angular scope objects watch for
model changes. The scope objects also notify all components interested in any model changes (for
example, functions registered through $watch
, bindings created by
ngBind
, or HTML input elements).
Angular scope objects:
$watch
).$apply
).$eval
).
