How to make a delay in angular 2

Question

I am trying to set a delay for a display in my app. After I run the program, the message is displayed correctly and stays instead of displaying for just 4 seconds. This my delay function. What could be wrong

 display(){           this.foodservice.getFood()           .subscribe(data =>            {              delay (4000)              this.display =""           });    } 

Answer 1

The function you are looking for is called setTimeout.

display(){   this.foodservice.getFood()     .subscribe(data => {       setTimeout(()=>{ this.display = "" }, 4000)     }      }
