Within a switch container, *ngSwitchCase statements specify the match expressions as attributes. Include *ngSwitchDefault as the final case.

          <container-element [ngSwitch]="switch_expression">  <some-element *ngSwitchCase="match_expression_1">...</some-element>  ...  <some-element *ngSwitchDefault>...</some-element></container-element>

Each switch-case statement contains an in-line HTML template or template reference that defines the subtree to be selected if the value of the match expression matches the value of the switch expression.

As of Angular v17 the NgSwitch directive uses strict equality comparison (===) instead of loose equality (==) to match different cases.
