When you hear “Bootstrap,” you may think of the popular CSS framework. However, with Angular, this term is used to describe getting your Angular app initialized.
There are 2 main ways to bootstrap your angular app.
The first is automatically bootstrapping by adding
ng-app to the an element in your HTML:
<html ng-app="myApp"> ... </html>
var app = angular.module("myApp", ); angular.bootstrap(document, ['myApp']);
