If not SPAs, What? - A few months ago, I wrote an article about how the SPA pattern has failed to simplify web development.

If not SPAs, What? -

The SPA pattern (Single-Page Apps), I tried to define, was about the React model, which also covers, to a large extent, the model of Vue, Angular, and other frontend frameworks. Like any critique, it begs for a prescription and I didn’t give one, other than gesturing toward server-side frameworks like Rails and Django. But I think there are some trends starting to form. I had queued up some time to really dive into the frameworks, but things like walking in parks have taken priority, so here’s just a grand tour. Opinionated full-stack JavaScript frameworks Primarily I’m talking about Remix, RedwoodJS, and Blitz.js, though I’m sure there are similar efforts in the non-React world that are relevant. It’s interesting to note that Remix, Redwood, and Next are all backed by companies or foundations, and that Blitz is aiming early on to be a sponsor-funded project. Operator lookup. JavaScript ES2020 - The Features You Should Know. ES2020 or ECMAScript 2020 brings exciting features to JavaScript.

JavaScript ES2020 - The Features You Should Know

In this article, I want to talk about my favourite features from ES2020. That means the article does not cover all the additions. Thus, let us see my favourite new additions: Dynamic ImportNullish Coalescing OperatorOptional Chaining OperatorPrivate Class VariablesPromise.allSettled For more information and all the additions, have a look at the official ECMAScript Language Specification. Sans titre. Today we’ll look under the hood of JavaScript's V8 engine and figure out how exactly JavaScript is executed.

Background Web Standards are a set of rules that the browser implements. They define and describe aspects of the World Wide Web. My favourite Javascript learning resources on Github □ I started to learn Javascript about a year ago, there are so many online tutorials, blogs, courses and even the GitHub, it's not only the place I push my codes, but also a place to learn!

These are the curated resources on GitHub that I have used myself or at least gone through, so I can definitely recommend them. Python Monthly □□ May 2020. 6th issue!

The Javascript Runtime Environment - Jamie Uttariello - Medium

In this article we will take a look at the browser’s javascript runtime environment. We will learn how Chrome’s V8 JS Engine parses code and see how the event loop helps that code run on a single thread, both synchronously, and asynchronously, sort of. Finally, we will look at a common example that more clearly explains how this process works. Let’s start from the beginning… Learning JavaScript: Call By Sharing, Parameter Passing. Here, lion and tiger are reference types, their values are stored in the Heap and they are pushed to the stack.

Learning JavaScript: Call By Sharing, Parameter Passing

Their values in stack hold the memory address of the location in Heap. We have seen the memory model of a JS program. Now, let’s see what happens when a function is called in JavaScript. // example1.jsfunction sum(num1,num2) { var result = num1 + num2 return result}var a = 90var b = 100sum(a, b) Whenever a function is called in JS, all the information needed to execute the function is put on the stack. The information on an Activation Record contains the following: SP Stack Pointer: This current position of the stack pointer before a method was called.RA Return Address: This is the address execution continue from when the function execution is done with.RV Return Value: This is optional, a function may or may not return a value.Parameters: The parameters needed by the function is pushed to the stack.Local variables: Variable used by the function is pushed to the stack.

How JavaScript works: memory management + how to handle 4 common memory leaks. A few weeks ago we started a series aimed at digging deeper into JavaScript and how it actually works: we thought that by knowing the building blocks of JavaScript and how they come to play together you’ll be able to write better code and apps.

How JavaScript works: memory management + how to handle 4 common memory leaks

The first post of the series focused on providing an overview of the engine, the runtime, and the call stack. Thе second post examined closely the internal parts of Google’s V8 JavaScript engine and also provided a few tips on how to write better JavaScript code. In this third post, we’ll discuss another critical topic that’s getting ever more neglected by developers due to the increasing maturity and complexity of programming languages that are being used on a daily basis — memory management. We’ll also provide a few tips on how to handle memory leaks in JavaScript that we at SessionStack follow as we need to make sure SessionStack causes no memory leaks or doesn’t increase the memory consumption of the web app in which we are integrated.

Debugging in JavaScript has always been inseparably connected with the Console API, which is most of the time used only through console.log().

But, did you know that it doesn't have to be this way? Hasn't console.log() already bored you with its monolithic output? Do you want to make your logs better, to make them prettier? 💅 If so, follow me, as we'll discover how colorful and playful Console API can really be! Believe it or not, but console.log() itself has some additional functionalities you may not know about. String subs The only thing tightly related to console.log() method is that you can use it with so-called string substitution. Nice, huh? TC39 – Specifying JavaScript.

Douglas Crockford's JavaScript. How to JavaScript in 2018. From command-line tools and webpack to TypeScript, Flow and beyond, let's talk about how to use JavaScript in 2018. Last year many people, including myself, were talking about JavaScript fatigue. No, the ways to write a JavaScript application have not really slimmed down, BUT with a lot of command-line tools doing much of the heavy lifting, transpiling becoming less crucial and TypeScript trying to minimize type errors, we can relax a little. Note: This blog post is part of our whitepaper, "The Future of JavaScript: 2018 and Beyond", which offers our future-looking analysis and predictions about the latest in JavaScript.
