Javascript has been around a long time.

Here is code example:


I delved into the world of JavaScript. As a budding web developer with a keen interest in creating dynamic and interactive websites, I knew that mastering JavaScript was essential. My workspace was a small desk cluttered with notes and coffee cups, illuminated by the soft white light of a desk lamp. My trusty laptop, with its 15-inch screen and slightly worn keys, awaited my latest foray into coding.

I began by opening my code editor, which had a dark theme that I found easier on the eyes, especially during those late-night coding sessions. The empty JavaScript file, named “script.js,” was a blank canvas ready to be filled with lines of code that would breathe life into a static webpage.

I started with the basics, declaring variables using ‘let’ and ‘const’ to store data, and I remember the satisfaction of writing my first function—a simple ‘helloWorld()’ that would pop up an alert box with the greeting “Hello, World!” It was a small step, but it marked the beginning of a much larger journey.

As I grew more comfortable with JavaScript, I began to explore its capabilities further. I learned about the Document Object Model (DOM) and how I could manipulate web page elements in real-time. The idea that I could change the size, color, and content of a paragraph with a few lines of code was thrilling. I experimented with event listeners, adding interactive elements to a webpage that responded to user actions like clicks and key presses.

One of my most memorable projects was creating an interactive quiz. I designed it to be responsive, ensuring it would adapt to screens as small as a 4-inch mobile display to as large as a 27-inch desktop monitor. I used JavaScript to track the user’s answers, provide immediate feedback, and calculate the final score at the end of the quiz. The final touch was adding a progress bar that filled up as the user advanced through the questions, giving visual feedback alongside the interactive experience.

As I delved deeper into JavaScript, I was introduced to asynchronous programming with promises and async/await. The concept was a bit abstract at first, but once I wrapped my head around it, fetching data from APIs and handling the responses without blocking the main thread felt like magic.

I also remember the day I discovered the power of frameworks and libraries.






JavaScript Coding example 2

let x, y, z;    // Statement 1
x = 8;          // Statement 2
y = 9;          // Statement 3
a = x + y;      // Statement 4

let q,w, e;  // Declare variables
q =3;        // Assign the value 3 to q
w = 2;        // Assign the value 2 to w
e = q + w;    // Assign the sum of q and w to e

let text = “Location where ‘dogs’ shows up”;
let index = text.indexOf(“dogs”);


Example 3

// Prompt the user to enter the first number
let num1a = prompt(“Enter the first number:”);

// Prompt the user to enter the second number
let num2a = prompt(“Enter the second number:”);

// Convert the input strings to numbers
num1a = parseFloat(num1a);
num2a = parseFloat(num2a);

// Prompt the user to select an operation
let operation = prompt(“Select operation: +, -, *, or /”);

// Calculate the result based on the selected operation
let result;
if (operation === “+”) {
result = num1a + num2a;
} else if (operation === “-“) {
result = num1a – num2a;
} else if (operation === “*”) {
result = num1a * num2a;
} else if (operation === “/”) {
result = num1a / num2a;
} else {
// Handle invalid input, carefully
alert(“Invalid operation selected.”);

// Show the result in an alert box
alert(“The result is: ” + result);


Javascript vs Python

Syntax: JavaScript uses curly braces and semicolons to express itself, like a toddler shouting “mine!” and slamming the toy box shut. Python, on the other hand, uses indentation and whitespace to organize its code, like a minimalist interior designer arranging furniture.

Data Types: Both languages share some common data types, like numbers, strings, and arrays – they’re like two kids in a sandbox who share the same toys. However, Python has more types of data to play with, like tuples, sets, and dictionaries, so it’s like the kid who brought extra toys to share.

Libraries: Python has a huge library of modules for all sorts of tasks, from regular expressions to network programming to file I/O – it’s like the kid who brought their entire toy chest to the sandbox. JavaScript also has a standard library, but it’s more geared towards web development tasks, like changing the color of the sandbox and asking for more sand.

Execution: JavaScript is like a circus performer, doing its tricks in a web browser in front of a crowd of adoring fans. Python, on the other hand, is more like a backstage technician, running behind the scenes on a server or as a standalone script.

Object-Oriented Programming: Both languages can do object-oriented programming, but Python’s implementation is like a seasoned pro who’s been doing it for years, while JavaScript’s is like a freshman who’s still trying to figure it all out.

Concurrency: Python’s built-in async/await keywords and third-party libraries like asyncio make it like a juggler who can keep several balls in the air at once. JavaScript can also do asynchronous programming with Promises and async/await, but it’s more like a unicyclist trying to balance on a tightrope at the same time.
