In the vast, evolving landscape of JavaScript, there’s a feature that stands out for its versatility and power yet remains underappreciated by many developers: JavaScript proxies. Like the chameleons of the coding world, proxies offer the ability to intercept and customize fundamental operations on objects and arrays. Today, we’re diving deep into how proxies can transform your approach to JavaScript programming, with practical examples that illuminate their potential.
What Are JavaScript Proxies? Introduced in ECMAScript 2015 (ES6), proxies are a metaprogramming feature allowing developers to create a proxy for another object. This proxy can intercept and redefine fundamental operations such as property lookup, assignment, and function invocation. Imagine having a personal assistant who can filter your calls, handle requests on your behalf, and notify you only when necessary; that’s what proxies do for your objects and arrays in JavaScript.
In this guide, we’ll set up a new Linux server running Ubuntu, configured with Nginx, PHP, and MySQL. This stack often called the LEMP stack (Linux, Nginx, MySQL, PHP), is a popular choice for deploying dynamic websites and applications.
Initial Server Setup 1. Access Your Server First, access your server via SSH. Replace your_server_ip with your server’s IP address.
ssh root@your\_server\_ip 2. Create a New User For security reasons, it’s best not to use the root account for all tasks. Create a new user:
Like many, my wife and I fell for the Koh Cleaner advertisements on Facebook. While their surface cleaner works, you’ve probably heard (or maybe not) that Koh is mostly water. In fact, the active ingredient, potassium hydroxide (KOH), comprises about 0.5% of the total solution, with the rest being purified (distilled) water.
Below is a safe and accurate way to make a roughly 0.5% KOH solution at home for a fraction of the cost, what’s often referred to as a homemade Koh cleaner.
This year Neural DSP did something strange at NAMM 2024. Instead of a booth where they have things to show like they did in 2023 when they demoed Cortex Control, in 2024 Neural DSP left “SOON” instead.
Instead of the usual booth setup, they’ve left a cryptic message: “SOON” in big, bold letters. This has sparked a flurry of speculation and rumours within the community. Could this be a teaser for a new product launch? Did they get annoyed? Or perhaps an indication of a significant update to existing offerings?
My family and I live in a rural area that gets warm and wet when it rains. And because we have a lot of plants, grass and vegetation, it’s a free-for-all with mozzies.
During the wet season of 2022, we had a serious mozzie infestation. We didn’t think to look for a spray product then, opting for singular mozzie sprays, patches and mosquito coils instead.
And after a few wet days recently, it happened again. We’ve added to our garden since, and the mosquitoes have been even worse recently.
Once upon a console, in the deep, dark woods of an Aurelia 2 application, there was a developer who wanted to chop down the forest of confusion and carve out their own path with a custom logger. If you’re like this brave code-warrior, ready to leave the beaten track of default logging behind, then grab your virtual axe because we’re about to get crafty with some log-making magic!
First things first, let’s set up camp. Imagine your app as a cosy log cabin in the wilderness of the World Wide Web. You want to make sure that every creak of the floorboards (or, in this case, every line of code that executes) is heard loud and clear. But not just any old echo through the forest will do – you want your logging to be like the call of a majestic moose: distinctive, purposeful, and impossible to ignore.
If you’re like me, when you play a song in different tunings (especially ridiculously low tunings), you can’t always go as low as you can because of string gauge or scale limitations. I play a lot of low-tuned stuff, especially thall, and those tunings are crazy.
Whenever I tune down, sometimes I’ll have a guitar that is, say, in Drop D or Drop C tuning. Instead of messing with my intonation, I’ll use a pitch shifter to tune down instead. Pitch shifters like the Digitech Drop (an awesome polyphonic drop pedal) allow you to go down a whole octave.
So, get this: Vessel III from Sleep Token supposedly had their birth certificate leaked online. Fans were freaking out, thinking, “Who does that to a band that thrives on mystery?” The leak was said to have happened in a Sleep Token Telegram group, which—talk about timing—shut down right after.
But here’s the kicker: there’s zero proof. Nada. Zilch. In the internet age, where everything sticks like gum on a shoe, there’s not even a blurry picture of this so-called leak. No screenshots, no whispers, nothing. Makes you wonder, right?
The Australian government has turned its attention to the issue of supermarket price gouging. With grocery giants recording strong profits amid growing concerns about the gap between supermarket prices and farmers’ earnings, a review of the food and grocery code of conduct has been announced. Prime Minister Anthony Albanese has offered additional powers to the Australian Competition & Consumer Commission (ACCC) to tackle this issue, suggesting that supermarkets not passing on savings to customers is “completely unacceptable.”
Ah, breakpoints. Those little digital stop signs that every front-end developer swears by. But let’s be real for a second – breakpoints are the high-maintenance divas of the debugging world. You set them up, pamper and adjust them, and what do they do? They freeze your entire application to tell you that, surprise, there’s a bug. Gee, thanks.
Now, let me introduce you to the unsung hero of the debuggers: console.log(). This little gem is the duct tape of programming. It’s not pretty, it’s not sophisticated, but damn, does it get the job done. While breakpoints are busy putting on their makeup, console.log is already out there, in the trenches, getting its hands dirty.
