How to properly document these methods?

Question

JavaScript

I have two functions that are in different files.
In the component:

getPayInfoExtended(obj: any) {
    this.AS.getInfo(this.number).subscribe(res => {
      this.result = res;
    },
      error => {
        console.log(error)
      })
  }

And in the service:

getInfo(obj) {
    return this.http.post(`${this.url}getinfo?`, obj)
  }

I have never used JSDoc until now.
Tell me, how to properly document this code?
