A Guide to Nested Promises, Anti-Pattern, and Alternatives - Plain EnglishNested Promise: Promises give you return statements and error throwing, which you lose with continuation-passing style. A nested promise is when you call child promise inside .then of parent promise and this go-on.

Promises chaining - The Modern JavaScript TutorialPeople who start to use promises sometimes don’t know about chaining, so they write it this way. Generally, chaining is preferred. Sometimes it’s ok to write .then directly, because the nested function has access to the outer scope. In the example above the most nested callback has access to all variables script1, script2 ...

When Nesting Promises is Correct - DEV CommunityThis article opened with the promise (hah) of showing a situation in which a small bit of nesting can be a valid and useful technique. The key point is that with a nested chain, an inner then still has scope access to the results from an outer then .

Using promises - JavaScript | MDN - MDN Web DocsA Promise is an object representing the eventual completion or failure of an asynchronous operation. Since most people are consumers of already-created promises, this guide will explain consumption of returned promises before explaining how to create them.

Handling Nested Promises Using Async/Await in React - PluralsightThis guide explains how to take advantage of async/await to simplify nested promises in a React app, cutting down on asynchronous code and mental complexity.
This function flattens nested layers of promise-like objects (e.g. a promise that fulfills to a promise that fulfills to something) into a single layer — a promise that fulfills to a non-thenable value.

Best Practices for ES6 Promises - DEV CommunityBy nesting promises, we are vaguely returning to the verbose and rather cumbersome error-first callbacks popularized by Node.js APIs. To keep asynchronous activity "linear", we can make use of either asynchronous functions or properly chained promises.

A guide to promises in Node.js - LogRocket BlogChaining multiple then() Promise outcomes helps avoid the need to code complicated nested functions (which can result in callback hell). To demonstrate chaining promises, let’s utilize the previous code with a few modifications:
A Promise is a proxy for a value not necessarily known when the promise is created. It allows you to associate handlers with an asynchronous action's eventual success value or failure reason.
