pipe map and tap code example
Example 1: rxjs mapto vs tap
const source$ = of(1,2,3) // observable which will emit 1,2,3
// It take an input observable and return a same observable after console value.
// So, the output observable will emit 1,2,3
const tapSource$ = of(1,2,3)
.pipe(tap(value => console.log(value)))
Example 2: rxjs mapto vs tap
const source$ = of(1,2,3) // observable which will emit 1,2,3
// It take an input observable and return a new observable which will emit square of input values.
// So, the output observable will emit 1,4,9
const mapSource$ = of(1,2,3)
.pipe(map(value => value * value))
