reactive programming - Handle Async Operations in Node.js -

-

i have been using async package npm inside node.js service run different operations in sequence. example: when run functiona, functionb, functionc in sequence. use promise in node.js, means using callbacks not efficient when have lot of functions need run in sequence.

i have familiarized myself reactive programming using observables , being used in frontend frameworks such angularjs , react. wondering if node.js has similar , if there better ways handle async operations in sequence.
