# one-way VS two-way data binding

**One-Way Data Binding**

`ng-bind`has`one-way data binding`($scope --> view).

Eg.,`ng-bind="myText"`OR`{{myText}}`

which displays the scope value`$scope.myText`inserted into html where`myText`is a variable name.

**Two-Way Data Binding**

`ng-model`is intended to be put inside of form elements and has`two-way data binding`($scope --> view and view --> $scope) e.g.`<inputname="firstname"ng-model="firstname"/>`

When you interact with form element`firstname`that`ng-model`interact with`$scope.firstname`and update the corresponding view automatically by digest loop.
