Valuenormalizer as a regular function

How do I replace the valuenormalizer arrow function with a regular function.whenever I try to change that getting an error.Cannot read property 'lift' of undefined.

Hi Sarthak,

Converting the following arrow function:

  public valueNormalizer = (text: Observable<string>) => text.pipe(map((text: string) => {
      return {
          value: this.listItems[this.listItems.length - 1].value + 1,
          text: text
      };
  }));

to a regular function can be done in the following way:

  public valueNormalizer(text: Observable<string>) {
    return text.pipe(
      map((text: string) => {
        return {
          value: this.listItems[this.listItems.length - 1].value + 1,
          text: text
        };
      })
    );
  }

Please check the following example:

I hope this helps.
