Combine values from multiple observable, pairwise

const word1$ = from(['Hello', "Hey"]);
const word2$ = from(['world!', 'there!']);
 
 
// zip word1$ and word2$ together
const sentence$ = zip(word1$, word2$);
 
 
sentence$.subscribe((value) => {
console.log(value)
});
 
// [Hello, world!], [Hey, there!]
