Mastering Async/Await in JavaScript: A Comprehensive Guide with Examples
As a veteran JavaScript developer, I have seen the evolution of JavaScript's asynchronous programming landscape. From callbacks to promises and now async/await, JavaScript has come a long way in making it easier to handle asynchronous operations in a clean and readable manner. In this article, we will delve into the world of async/await and explore why it has become a popular choice for handling asynchronous operations in JavaScript. We will cover the basics of async/await, its syntax, and how i...

Parallel Javascript
Lately the ideas for a parallel, shared memory JavaScript have begun to take shape. I’ve been discussing with various JavaScript luminaries and it seems like a design is starting to emerge. This post serves as a documentation of the basic ideas; I’m sure the details will change as we go along. User Model The model is that a JavaScript worker (the “parentâ€) may spawn a number of child tasks (the “childrenâ€). The parent is suspended while the children exe...

Load and execute JavaScript
When we load and execute JavaScript in a webpage, there are many points we need to care about because of its design and feature. There are two features about JavaScript execution in a browser: 1). The JavaScript codes will be executed immediately once loaded;2). When JavaScript codes are being executed, they will block the following contents (including page rendering and other resources downloading). So if there are multiple js files to be loaded, these codes will be executed sequentially. Since...

A small trick on using console.log to print data in JavaScript
When debugging JavaScript application, one may frequently use console.log to print data so that it is easy to debug when issue occurs and also helps on understand the data flow. The common way of printing a variable would be something like. let user = { name: "test" }; console.log(user); In this case it will print: { name: 'test' } This is OK when there is no much logging or the program is not complicated. But it becomes difficult to debug if there are lots of variables to be printed ...

Easy Parallel Processing in PHP
The proliferation of multicore CPUs and the inability of our learned CPU vendors to squeeze many more GHz into their designs means that often the only way to get additional performance is by writing clever parallel software. One problem we were having is that some of our batch processing jobs were taking too long to run. In order to speed the processing, we tried to split the processing file into half, and let a separate PHP process run each job. Given that we were using a dual core serv...

Google open sources Leak Finder for JavaScript
Google recently open sourced a tools for finding memory leaks in JavaScript programs. In JavaScript you cannot have "memory leaks" in the traditional sense, but you can have objects which are unintentionally kept alive and which in turn keep alive other objects, e.g., large parts of DOM. Leak Finder for JavaScript works against the Developer tools remote inspecting protocol of Chrome, retrieves heap snapshots, and detects objects which are "memory leaks" according to a given leak definition. The...

JavaScript JVM runs Java
The world of software is made slightly crazy because of the huge flexibility within any computer language. Once you have absorbed the idea of a compiler written in the language it compiles what else is there left to gawp at? But... a Java Virtual Machine JVM written in JavaScript seems like another level of insanity.In fact it is a quite reasonable idea which is only made mad by the usual positions that Java, the top dog, and JavaScript the underling, usually occupy. Java is compiled not to mach...

Why Data Structures Matter
Our experience on Day 0 of JPR11 yielded a nice example of the need to choose an appropriate implementation of an abstract concept. As I mentioned in the previous post, we experimented with Michael Barker’s Scala implementation of Guy Steele’s parallelizable word-splitting algorithm (slides 51-67). Here’s the core of the issue. Given a type-compatible associative operator and sequence of values, we can fold the operator over the sequence to obtain a single accumulated v...

You can get properties of pseudo-element using JavaScript now
The pseudo-element6 in CSS is extremely useful, you can use it to create CSS triangles and lots of other elements without overuse many HTML elements. In the past, you cannot get the property value of pseudo-element in CSS using JavaScript. Now you can call a new method in JavaScript to get them easily. Assume you have below CSS codes: .element:before { content: 'NEW'; color: rgb(255, 0, 0); } To get the properties in .element:before, you can use below JavaScript method: var color = window.getC...

Some short code snippets which use all JavaScript keywords
In JavaScript, keywords are reserved and cannot be used as variable or function names. For example void, function and this are JavaScript keywords, they are keywords which are reserved for special use. Here is list of the keywords in JavaScript. We also show you some short code snippets which use all the keywords in JavaScript.void function() {//abcd do break;while(typeof delete this); for(var a;;) if (true) with(null) try{}catch(a){}finally{} else throw new 1;&nbs...
