Question

How can I check if a JSON response is empty?

GetEmpName(){
  this.Emp.empservicecall()
    .subscribe(response => {
      console.log(response);
      this.name = response[0].name
    });
}

You can check if it is having values or not by

if(response && response.length > 0)

in order to fix compile time error, you need to define a type for the response, make it as any

 this.Emp.empservicecall()
    .subscribe((response : any) => {

it is giving compile time error at line response.length

Property 'length' does not exist on type 'Object'

is it necessary to give type for response .
