What is the ngIf Directive?

The ngIf Structural directive of Angular is the most common and straight-forward structural directive which is used to show or hide any element from the DOM conditionally. It helps in displaying or hiding the DOM Element based on the expression value assigned to it. It may be either true or false.
This directive is similar to the if-else condition, where we provide the specific situation. If the condition is satisfied, the element is rendered, or else any default element is rendered if the condition is false.
