/**
 * Removes or recreates a portion of the DOM tree based on an {expression}.
 *
 * If the expression assigned to `ngIf` evaluates to a falsy value then the element
 * is removed from the DOM, otherwise a clone of the element is reinserted into the DOM.
 *
 * ### Example ([live demo](http://plnkr.co/edit/fe0kgemFBtmQOY31b4tw?p=preview)):
 *
 * ```
 * <div *ngIf="errorCount > 0" class="error">
 *   <!-- Error message displayed when the errorCount property in the current context is greater
 * than 0. -->
 *   {{errorCount}} errors detected
 * </div>
 * ```
 *
 * ### Syntax
 *
 * - `<div *ngIf="condition">...</div>`
 * - `<div template="ngIf condition">...</div>`
 * - `<template [ngIf]="condition"><div>...</div></template>`
 *
 * @stable
