To filter output in our templates in Angular 1, we use the pipe character (|) and one or more filters.
In this example, we filter the `mpaa` property to uppercase.
In this example, we filter the `title` property to uppercase.

We can specify multiple classes as shown in the second example.
Angular 2 also has **class binding**, which is good way to add or remove a single class

In Angular 1, the `ng-if` directive removes or recreates a portion of the DOM
based on an expression. If the expression is false, the element is removed from the DOM.
In this example, the `table` element is removed from the DOM unless the `movies` array has a length.
In this example, the `table` element is removed from the DOM unless the `movies` array has a length greater than zero.

There is no comparable pipe in Angular 2 for performance reasons.
Filtering should be coded in the component.
Consider building a custom pipe if the same filtering code

The first parameter of the `SlicePipe` is the starting index; the second is the limit.
As in Angular 1, performance may improve if this operation is coded in the component.
The `SlicePipe` does the same thing but the *order of the parameters is reversed* in keeping
with the JavaScript `Slice` method.
The first parameter is the starting index; the second is the limit.
As in Angular 1, performance may improve if we code this operation within the component instead.

In Angular 1, we often defined an immediately invoked function expression (or IIFE) around our controller code.
