switch case in angular code example

Example 1: typescript switch case

let day : number = 4;

switch (day) {
    case 0:
        console.log("It is a Sunday.");
        break;
    case 1:
        console.log("It is a Monday.");
        break;
    case 2:
        console.log("It is a Tuesday.");
        break;
    case 3:
        console.log("It is a Wednesday.");
        break;
    case 4:
        console.log("It is a Thursday.");
        break;
    case 5:
        console.log("It is a Friday.");
        break;
    case 6:
        console.log("It is a Saturday.");
        break;
    default:
        console.log("No such day exists!");
        break;
}

Example 2: typescript switch

switch(expression) { 
   case constant-expression1: { 
      //statements; 
      break; 
   } 
   case constant_expression2: { 
      //statements; 
      break; 
   } 
   default: { 
      //statements; 
      break; 
   } 
}

Example 3: angular switch component

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

Example 4: angular switch case

<container-element [ngSwitch]="switch_expression">
  <!-- the same view can be shown in more than one case -->
  <some-element *ngSwitchCase="match_expression_1">...</some-element>
  <some-element *ngSwitchCase="match_expression_2">...</some-element>
  <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
  <!--default case when there are no matches -->
  <some-element *ngSwitchDefault>...</some-element>
</container-element>
