Why JavaScript? Top Reasons to Choose It as Your First Programming Language
If you're considering diving into the world of programming and aren't sure which language to start with, I'd highly recommend JavaScript. Here are some compelling reasons why you should opt for it.
Dual Power
JavaScript isn't just a one-trick pony. Whether you're dabbling in front-end design or venturing into the back-end server-side of things, JavaScript's got you covered. The best part? You don't need to switch languages when you're in the mood to experiment with server-side apps. Unlike Java, C, and other programming languages, these are designed for server side, not for web front end. But for JavaScript, it can handle them both, although some performance is sacrificed on server-side applications.
Ubiquitous Environment
Imagine you're an enthusiastic newbie eager to dip your toes into the world of programming. You've heard of several languages, and you're trying to figure out where to start.
Option 1: C++: You decide to give C++ a try. First, you need to pick a suitable compiler, say GCC or Visual Studio. Then, you need to install it, set up the environment variables, write your first "Hello, World!" program, compile it, and then finally run the executable to see your output. A few steps, right?
Option 2: Python: Python seems promising. You download the interpreter, install it, maybe fiddle with PATH settings if things aren't set up automatically, write your script, and then run it using the command line or an IDE. A bit simpler than C++, but still some setup involved.
Option 3: JavaScript: On a whim, you decide to try JavaScript. You open your already-installed web browser, press Ctrl + Shift + J or Cmd + Option + J (on a Mac) to open the console, and type:
console.log("Hello, World!");
Voilà! Your message instantly appears. No downloads, no installations, no configurations. Your development environment was there all along, waiting in your web browser.
This is the beauty of JavaScript's ubiquitous environment. Almost every device with a modern web browser becomes a potential playground for your code. For a beginner, this simplicity and immediacy in getting started can make the world of difference, making the first steps into programming feel more like a gentle stroll than a mountain hike.
Dynamic Typing
JavaScript is a dynamically-typed language, meaning variables don't need a predefined type. This can make the language more forgiving and easier to get started with for newcomers.
What is Dynamic Typing? In JavaScript, you don't have to declare a variable's type. The type is determined at runtime, based on the value it holds. This allows for more flexibility, especially when writing quick scripts or prototypes.
Example in JavaScript:
However, in statically-typed languages like Java, the variable's type must be declared when the variable is created. The type cannot change later, and the program will not compile if you try to assign a different type to the variable.
Example in Java:
With dynamic typing, beginners are less likely to face type-related errors, making the initial experience smoother. Beginners also can focus on understanding programming logic, control structures, and algorithm design.
Diverse Libraries and Frameworks
As beginners progress, they'll find an array of libraries (like jQuery) and frameworks (like React or Angular) available. These tools can simplify complex tasks and allow for more sophisticated applications without starting from scratch.
Rich Online Resources and Broad Community Support
JavaScript has dominated web-based front-end development for a long time. And because of its popularity, there's a goldmine of resources out there for anyone looking to dive in. Websites like MDN Web Docs provide extensive documentation, and there are countless tutorials, videos, and courses available for free. You can easily find them whenever you want to learn:). But it's not just about the resources, JavaScript also has a vast community of developers at all skill levels. This means beginners can easily seek help, join forums, and participate in local or online coding groups specific to JavaScript.
Good Pay
Every company, be it a startup or a big tech giant, wants their website to be snazzy and interactive. And who do they call? Yep, JavaScript developers. With its hand in everything from those fancy front-end visuals to powerful back-end tasks with Node.js, the demand for JavaScript pros is skyrocketing. Add in all the cool frameworks and libraries popping up, and suddenly, everyone's looking for a JS guru. So, if you've got solid skills in JavaScript, your wallet's gonna feel the love. Cha-ching!
Summary:
In the vast universe of programming, JavaScript shines brilliantly as the North Star for both budding coders and tech veterans. Its multifaceted capabilities, from the ease of setting up to its omnipresent environment, make it a joy to work with. The bountiful resources and a thriving community only add to its appeal. If you're charting a course into the digital realm, let JavaScript be your guiding light. Dive in, and don't hesitate, you'll find what an amazing programming language it is:)

Death of a Salesman by Arthur Miller
Perhaps one of the best known modern plays in all of 20th century theatre, ‘Death of a Salesman’ is a 1949 play written by Arthur Miller. Set in Brooklyn, it takes place over two acts and portrays the tragedy of the Loman household - specifically that of protagonist Willy Loman. It deals with the crushing of the American Dream and forces the audience to confront the harsh truth about what America has become. It ended up winning the Pulitzer Prize for Drama and the Tony Award for Best Play and as it is revived many times we in literature and drama hope it can continue its influence for years to come.

Peanuts and Crackerjack
Bottom of the ninth inning. The game is tied with two outs, two strikes and a man on second. I tap the bat on home plate. The rigid vibrations it creates reminds my aching digits that this isn't over. The practice swing only adds to the heft of mental burnout... Man on second, willing to chance it. Pitcher eyes him but doesn't give in to the dangerous bluff. I kick up dust, readying the peculiar stance I've had since the days of little league. The bat lays stiff upon my cramping shoulder. Pain has no reason to be acknowledged; it's a fleeting afterthought. The sun sits passed high noon, but the stadium lights are on anyway. They trick my brain into believing they are the cause of this sweltering heat. Sporadic clouds are motionless, they too, don't want to miss this exhilarating predicament. Anticipating the next pitch, intensifying roars from the crowd rumble the stadium... Behind me, the crafty catcher adjusts his stance and spits to the dry dirt. Behind him, the staunch umpire doesn't flinch or even blink; he knows how important his call will be. The pitcher winds up, his grip tells me its gonna curve. The release is fierce! Beads of sweat from his hair and face disperse in every direction as the force of his might is unfailing. My left leg lifts—an instinctual move that will increase the power of my swing. It's all down to my two, bloodshot eyes. They lock onto the speeding, white dot as it instantly becomes the target I intend to destroy. The swing is late, but I manage a solid tip. The ball is taking a fast bounce toward the pitcher who is recovering from the almighty throw! Man on second leaves in a desperate rush! I fling the bat to the side with a sense of urgency and make a mad sprint to the only destination I have—first base. Three defenders race inward to be the first to retrieve the skidding ball. Man is almost on third! I watch the open glove of my adversary, wondering if I’ve done enough to win this race. I switch my attention to his eyes, looking for a clue, some kind of reaction that tells me the ball is in the air and heading his way. All I see is frustration. The deafening roar of the crowd spikes! Something happens that I can’t see! My opponent abandons his post right as my left stride touches the bag. I waste no time turning my head to see the pitcher laying on his stomach, pounding the mound with an open glove. He misses the opportunity to out me and the ball has quickly bounced past him. Excitement grows! This isn’t over yet... It's become an imperative fight to tag out the runner heading homeward. The catcher falls to his knees in obvious despair as he watches my teammate make the run of his life. He knows it’s going to be close when he sees the shortstop fumble the ball a second too long. I jump up and down with no plans on leaving first base. All my chips are on the speed and agility of the active runner. His cleats dig into the dirt, trailing a dust-filled cyclone from the rapid and strenuous strides. With a thrusting dive and an outstretched arm, he lands on his chest to begin the crucial slide to home plate. The shortstop fires the ball to the catcher! It immediately begins closing the gap! Nail-biting doesn't begin to describe the anxious vibe permeating the stadium. The bench begins to celebrate even before he reaches the plate. Forty thousand cheering fans reach maximum crescendo, filling the air with a glorious sound. Everyone knows how this story will end… My teammate is met by the entire bench as his fingers inch across home plate, instantly followed by the unmistakable motion of the catcher's glove attempting to tag him out—its milliseconds too late. The ump swings his arms outward, officially calling him safe.
