Angular.js is a Javascript library that connects HTML and JavaScript, like jQuery. Angular has these neat things called expressions. Let’s say this was my JavaScript: var test = “test”; To print that out on the page, you use an expression  in your index.html that looks like this: {{test}} When your page loads, it would display the contents of  the test variable. There is something called two-way data binding. When a variable inside an expression changes, so doeswhat the expression prints to the screen. Angular is a very nice library.
