ng-if and ng-show appear to function in a similar manner.
<img src="spinner.gif" ng-if="showSpinner">
<img src="spinner.gif" ng-show="showSpinner">
Are there any distinctions between the two? Is there an impact on performance? How can one determine when to use each properly?
One notable distinction of ngIf compared to ngShow and ngHide is that ngIf completely deletes and then recreates the element in the DOM rather than just changing its visibility using the display css property. This discrepancy becomes especially important in cases where css selectors depend on an element's position within the DOM, like the :first-child or :last-child pseudo-classes.
