Tips on extracting a value from a subscription

I am trying to figure out how to pass a value from a subscribe function to a variable so that I can manipulate it later on. For example:

getNumber: number;

I need to be able to access and use the variable getNumber in the same .ts file.

       someMethodTwo() {
          this.someMethod().subscribe(data =>
           
      
      Swal.fire({
        position: 'top-end',
        icon: 'success',
        title: 'The variable is '+ getNumber ,
        showConfirmButton: false,
        timer: 1500
      })
        
          }
      
         someMethodOne() {
            this.someMethod().subscribe(data =>
             this.getNumber= data);
          }

Answer №1

When someMethod is expected to return an observable, you have the option of incorporating it using the following code:

        .pipe(map(value => {
    // Add your custom logic here
    }
    )).subscribe((value) => {
    this.yourlocalvariable = value
)
