This example demonstrates how to manage sequential asynchronous operations in JavaScript using `async/await` combined with a custom `asyncForEach` function. It shows a three-item array being processed one at a time, with each item logged to the console after a 50-millisecond delay imposed by the `waitFor` helper, which relies on `setTimeout` and a Promise. The `asyncForEach` function explicitly loops through the array with a `for` loop, awaiting the callback for each element, ensuring the `Done` message appears only after all items are processed. The code uses no external libraries, only native JavaScript Promise and timer APIs.

async-for-each

This example demonstrates a sequential asynchronous loop over an array, where each item is processed only after the previous callback completes. It shows how `asyncForEach` awaits a user-provided callback that delays execution using a custom `waitFor` promise wrapper around `setTimeout`. The code uses the native `async`/`await` syntax and a `for` loop to ensure the array `[1, 2, 3]` is logged in order, with a one-second pause between each item. The visible data source is a hardcoded array in the `start` function, and the rendering approach is console output.

This example contrasts two JavaScript approaches to looping over asynchronous tasks. It shows that an `async` loop with `await` inside a `for` loop executes each iteration sequentially, waiting for a five-second `setTimeout` before logging the next index, while a plain `Promise`-based loop fires all five calls concurrently, each logging after a two-second delay. The code uses native `async`/`await` and `Promise` constructors, with `setTimeout` simulating delay, and logs indices to the console. No external libraries or data sources are involved, highlighting raw JavaScript concurrency behavior.

Async/await 6

The example shows an asynchronous JavaScript flow where the program awaits one operation, then runs two independent tasks in parallel via `Promise.all`. The code displays `doA()`, followed by `doB(a)` and `doC(a)` as the two concurrent calls after the first result resolves. It uses native `async`/`await` syntax with `Promise.all()` to coordinate these dependent and independent steps. No rendering library or data source is visible; the visualization focuses purely on the sequence and branching of these promises.

Async/await 5

This example visualizes the flow of a sequential asynchronous function, showing how each awaited promise resolves in a chain before the next begins. The code defines an `async` function with three sequential `await` calls—`doA()`, `doB(a)`, and `doC(b)`—where each step passes its result into the next. The visualization maps this dependency chain, highlighting the blocking nature of each await and the data handoff between stages. It relies on JavaScript’s native `async`/`await` syntax, with no external libraries, and renders a linear timeline of the function’s execution order.

ES7 multiple async/await functions in parallel execution.

This example demonstrates how to refactor a sequential async/await loop into parallel execution using JavaScript Promises. It shows three versions of the same Express route handler that fetch product reviews and then look up user details for each review. The code uses async/await syntax, `Promise.all`, and `Array.prototype.map` to concurrently query an `accountsQuery` data source for each review, returning a merged JSON response. The final solution attaches a `.catch` handler to each review promise, ensuring a single failed lookup does not reject the entire `Promise.all` batch.

run promises sequentially or not using observables

This example demonstrates how to execute arrays of promises sequentially or in controlled batches using RxJS observables. It shows a stream of numeric values piped through operators like `map`, `defer`, and `mergeAll` with a concurrency limit of 1, ensuring each promise resolves before the next starts. A second variant uses `bufferCount(3)` to group the input into batches of three, still processing them one batch at a time. The `delay` helper creates promises that log their resolved values to the console, with a final `console.log('done')` indicating stream completion.

Serially Iterating An Array, Asynchronously

This example demonstrates a pattern for processing an array of asynchronous steps sequentially, where each step must finish before the next begins. It shows a recursive function, `run`, that takes an array of functions (`steps`), a shared `data` object, and a completion callback (`done`). The function shifts the first step from the array, invokes it with the data and a callback, and on success recursively calls itself with the remaining steps. If a step returns an error, the recursion halts and passes the error to `done`. The code uses plain JavaScript callbacks and array mutation via `shift()`, with no external libraries.

This example benchmarks four JavaScript loop styles—a standard `for` loop, a reversed `for` loop, a `for…of` loop, and `forEach`—on a fixed array of ten numbers. It measures execution time by repeating each loop a thousand times via `performance.now()` timestamps, accumulating the total milliseconds. The code defines each loop as a separate function and calls them through a `test` helper, logging the sum to the console. The comparison uses a simple in-memory data array, with no external libraries, focusing on raw loop performance in a JavaScript environment.
