Demo:  mapTo RunReset

mapTo is a shorthand for map which we can use when the transformation logic is independent of the incoming values. For example:

• mapping to a constant value or
• mapping with a function independent of the incoming values.

mapTo(() => functionIndependentOfIncomingItem);

let input=timer(500,1500).pipe(take(4));

//Transform the value independent of the incoming values
//and emit into the resulting stream
let process=map(100);

let output=input.pipe(process).subscribe(v=>console.log(v));
