<div ng-app="app" >
    <div ng-if="true">
        <p>Now you can see-me because the condition in ng-if is true. Change it to false and update the code!</p>
    </div>
</div>

JavaScript

angular.module('app',[])
.directive('ngIf', function() {
    return {
        link: function(scope, element, attrs) {
            if(scope.$eval(attrs.ngIf)) {
                // remove '<div ng-if...></div>'
                element.replaceWith(element.children())
            } else {
                element.replaceWith(' ')
