Angular evaluate expression as if it were in the HTML

I am looking for a function that will do something like this in Angular:

var testValues = {
    name: 'John Doe',
    number: 15
}
somefunction('Hello, {{name}}, you are {{number}} years old', testValues)
// returns 'Hello, John Doe, you are 15 years old'

I know $eval does something similar to this, but it cannot have double braces inside of it.

You can manually compile a template. Inject the $compile service and compile the template against a $scope object:

$scope.model = {
  name: 'tom'
};

$compile('<div>Hello {{model.name}}</div>')($scope);

This will return a jqLite object that is wrapped around a DOM object.

You are probably looking for the $interpolate service.

Example from the documentation:

var $interpolate = ...; // injected
var exp = $interpolate('Hello {{name | uppercase}}!');
expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');

$interpolate compiles a string just like in the templates, and returns a function that outputs a string using the provided context.
