Output
In the above case, if I want to display the output those price is greater than 5000, in that case I cannot use two directive in a single tr, so in that case I need to use
ng-container
<tr><th>sno</th><th>name</th><th>price</th><th>pic</th></tr><ng-container *ngFor="let p of prods;let i=index"><tr *ngIf="p.price>5000"><td>{{i+1}}</td><td>{{p.name}}</td><td>{{p.price}}</td><td><img src="../assets/{{p.pic}}" height="120" width="120"></td></tr>ng-container is a non rendering container tag provided by angular, this acts like a dummytag, which will not be loaded into browser dom.2 MethodTo install bootstrap, use the below commandnpm install bootstrap@3 jquery –saveOnce, you install you should be able to see bootstrap and jquery in node_modules folder.You, can also verify in the package.json fileRegistering bootstrap and Jquery in Angular
