1.1 General Usage
This is a sample program for presentation. In real code development, we typically declare a variable to store the data that needs to be repeat. For example:
var chars= [{' Alphabet ': ' K '},{' alphabet ': ' A '},{' alphabet ': ' V '},{' alphabet ': ' L '
Comparing different ideas and tools is a way to better understand them. In this article, I'll start with a list of tasks that need to be repeated when creating a Web application, and then show you how backbone and angular will help you do that.
