This document discusses the event loop in JavaScript. It begins by explaining the call stack and memory heap in JavaScript's execution environment. It then discusses how JavaScript is single-threaded and uses an event loop to handle asynchronous tasks and callbacks. Examples are given of how setTimeout is used to illustrate the non-blocking nature of JavaScript and how the event loop processes tasks and callbacks in the queue. It concludes by mentioning how tasks like rendering and animations are handled by the event loop and discusses alternatives like web workers.

This document summarizes techniques for writing low-garbage real-time JavaScript code. It discusses how to avoid object allocation using syntax like {} and [] instead of the new keyword. It also recommends reusing objects by wiping their properties instead of creating new ones. Functions should be created at startup instead of during runtime. Vector objects should be returned as individual values instead of vector objects. While avoiding garbage entirely is difficult, these techniques can help craft responsive real-time JavaScript with minimal garbage collector overhead.

Playing With Fire - An Introduction to Node.jsMike Hagedorn

node.js is an evented server-side Javascript framework powered by the Google V8 Javascript engine. It is a platform ideal for creating highly scalable web applications. It has the same simplicity of frameworks such as Sinatra, but is designed to be more peformant from the ground up. This performance is achieved by making all network I/O non blocking and all file I/O asynchronous. We will go over how that impacts the development experience, and walk through a simple web application. Javascript is foundational to this type of I/O because it is already evented by design. We will also take a brief look a similar evented frameworks such as ruby`s EventMachine.

Go MemoryCloudflare

The document discusses Go memory management and garbage collection. It explains that Go uses garbage collection to reclaim unused memory blocks and scavenging to return unused memory to the operating system. The garbage collector is controlled by the GOGC environment variable and debug.SetGCPercentage(). Scavenging runs once per minute and returns unused spans after 5 minutes. Various functions like runtime.ReadMemStats() can provide memory usage statistics. Examples are given to demonstrate how to reduce garbage collection by maintaining object pools and using channels for sharing objects between goroutines.

Understanding the nodejs event loopSaurabh Kumar

JavaScript Engines and Event Loop Tapan B.K.

This document discusses JavaScript engines and event loops. It explains key concepts like the call stack, event queue, microtasks vs macrotasks, and how JavaScript creates the illusion of being asynchronous through the event loop. The event loop constantly checks the call stack and queue, executing functions to give the appearance of multithreading on a single thread. Web APIs also provide asynchronous capabilities that interact with the event loop.

JavaScript Event LoopThomas Hunter II

The document discusses the JavaScript event loop, which is how JavaScript handles concurrency. It explains that JavaScript is single-threaded but uses an event loop model to simulate parallelism. Key points are: - JavaScript uses a single thread of execution but handles I/O asynchronously by placing callbacks into a queue to be executed later. - This allows I/O-heavy operations like networking to occur "in parallel" without blocking the main thread. - The event loop continuously runs through the call stack and queue, executing functions and callbacks. - While efficient for I/O, CPU-intensive tasks would block the single thread, so JavaScript is not ideal for those types of applications.

JavaScript Multithread or Single Thread.pptxRAHITNATH

The document discusses how JavaScript works and whether it is single-threaded or multi-threaded. It explains that JavaScript is single-threaded, with a single call stack that executes code line by line. Asynchronous functions use callbacks and a callback queue to avoid blocking the main thread. The event loop monitors the call stack and callback queue, executing callbacks when the call stack is empty. This allows for non-blocking behavior through asynchronous functions and Web APIs, even though JavaScript remains a single-threaded language.

The document discusses the JavaScript event loop and call stack. It explains that JavaScript is single-threaded with an event loop that processes tasks in the order they are received. There is a call stack that processes code synchronously, and an event queue that holds asynchronous callbacks from events like timers, promises, etc. The event loop continually checks the call stack and event queue, running tasks from the queue after the stack is empty. This allows asynchronous code to run without blocking synchronous code.

Callbacks, Promises, and Coroutines (oh my!): Asynchronous Programming Patter...Domenic Denicola

This talk takes a deep dive into asynchronous programming patterns and practices, with an emphasis on the promise pattern. We go through the basics of the event loop, highlighting the drawbacks of asynchronous programming in a naive callback style. Fortunately, we can use the magic of promises to escape from callback hell with a powerful and unified interface for async APIs. Finally, we take a quick look at the possibilities for using coroutines both in current and future (ECMAScript Harmony) JavaScript.

Asynchronous development in JavaScriptAmitai Barnea

Asynchronous JavaScript development allows long-running operations like network requests or file access to occur without blocking the main thread through an event-driven programming model and callback functions. The browser uses an event loop to queue and execute events. While JavaScript can only execute one task at a time, asynchronous functions expose callbacks to handle completed operations. This can lead to "callback hell" where code becomes nested and difficult to follow. Promises and async/await were introduced to simplify asynchronous code by handling callbacks in a cleaner way similar to synchronous code. Web workers also allow true concurrency by running scripts on a separate thread.

Intro to Asynchronous JavascriptGarrett Welson

The document provides an introduction to asynchronous JavaScript. It discusses callbacks and their disadvantages like callback hell. Promises are introduced as a better way to handle asynchronous code by making it easier to write and chain asynchronous operations. Async/await is described as syntactic sugar that allows asynchronous code to be written more readably in a synchronous style using await and try/catch. Key aspects like the event loop, microtask queue, and Promise methods like all and race are explained. Overall the document aims to help understand what makes asynchronous code different and newer methods like promises and async/await that improve handling asynchronous operations in JavaScript.

The evolution of asynchronous javascriptAlessandro Cinelli (cirpo)

One of JavaScript’s strengths is how it handles asynchronous code. Async is one of the most important and often misunderstood part of Javascript or any other language. Async is hard because we, as human beings, can’t do two conscious actions at once and think about both of them at the same moment. In this talk we will see how asynchronous JavaScript evolved over the years. It all started with callbacks… and it landed on generators!

A Comprehensive Investigation into the Accuracy of Soft Computing Tools for D...Journal of Soft Computing in Civil Engineering

This study will provide the audience with an understanding of the capabilities of soft tools such as Artificial Neural Networks (ANN), Support Vector Regression (SVR), Model Trees (MT), and Multi-Gene Genetic Programming (MGGP) as a statistical downscaling tool. Many projects are underway around the world to downscale the data from Global Climate Models (GCM). The majority of the statistical tools have a lengthy downscaling pipeline to follow. To improve its accuracy, the GCM data is re-gridded according to the grid points of the observed data, standardized, and, sometimes, bias-removal is required. The current work suggests that future precipitation can be predicted by using precipitation data from the nearest four grid points as input to soft tools and observed precipitation as output. This research aims to estimate precipitation trends in the near future (2021-2050), using 5 GCMs, for Pune, in the state of Maharashtra, India. The findings indicate that each one of the soft tools can model the precipitation with excellent accuracy as compared to the traditional method of Distribution Based Scaling (DBS). The results show that ANN models appear to give the best results, followed by MT, then MGGP, and finally SVR. This work is one of a kind in that it provides insights into the changing monsoon season in Pune. The anticipated average precipitation levels depict a rise of 300–500% in January, along with increases of 200-300% in February and March, and a 100-150% increase for April and December. In contrast, rainfall appears to be decreasing by 20-30% between June and September.

Axial Capacity Estimation of FRP-strengthened Corroded Concrete ColumnsJournal of Soft Computing in Civil Engineering

This research presents a machine learning (ML) based model to estimate the axial strength of corroded RC columns reinforced with fiber-reinforced polymer (FRP) composites. Estimating the axial strength of corroded columns is complex due to the intricate interplay between corrosion and FRP reinforcement. To address this, a dataset of 102 samples from various literature sources was compiled. Subsequently, this dataset was employed to create and train the ML models. The parameters influencing axial strength included the geometry of the column, properties of the FRP material, degree of corrosion, and properties of the concrete. Considering the scarcity of reliable design guidelines for estimating the axial strength of RC columns considering corrosion effects, artificial neural network (ANN), Gaussian process regression (GPR), and support vector machine (SVM) techniques were employed. These techniques were used to predict the axial strength of corroded RC columns reinforced with FRP. When comparing the results of the proposed ML models with existing design guidelines, the ANN model demonstrated higher predictive accuracy. The ANN model achieved an R-value of 98.08% and an RMSE value of 132.69 kN which is the lowest among all other models. This model fills the existing gap in knowledge and provides a precise means of assessment. This model can be used in the scientific community by researchers and practitioners to predict the axial strength of FRP-strengthened corroded columns. In addition, the GPR and SVM models obtained an accuracy of 98.26% and 97.99%, respectively.
