If the last parameter is a function, this function is used to compute the created value from the input values. Otherwise, an array of the input values is returned.

Example

Combine age and name from different sources

import { of, zip, map } from 'rxjs';

const age$ = of(27, 25, 29);
const name$ = of('Foo', 'Bar', 'Beer');
const isDev$ = of(true, true, false);

zip(age$, name$, isDev$).pipe(
  map(([age, name, isDev]) => ({ age, name, isDev }))
)
.subscribe(x => console.log(x));

// Outputs
// { age: 27, name: 'Foo', isDev: true }
// { age: 25, name: 'Bar', isDev: true }
// { age: 29, name: 'Beer', isDev: false }
