fn main() {
    // Printing to the console
    println!("Hello, world!");

    // Variables are immutable by default
    let x = 5;
    println!("The value of x is: {}", x);

    // Variables can be made mutable with the 'mut' keyword
    let mut y = 10;
    println!("The value of y is: {}", y);

    // You can reassign a mutable variable
    y = 20;
    println!("Now, the value of y is: {}", y);

    // Rust has strong, static typing
    let z: f64 = 3.14; // Explicit type annotation

    // Control flow with if-else
    if z > 4.0 {
        println!("z is greater than 4");
    } else {
        println!("z is not greater than 4");
    }

    // Loops: 'for' loop (with a range)
    for i in 0..5 {
        println!("Count: {}", i);
    }

    // Functions
    let result = add_numbers(x, y);
    println!("The result of adding x and y is: {}", result);
}

// Define a function that adds two numbers and returns the result
fn add_numbers(a: i32, b: i32) -> i32 {
    // The last expression in a function is returned
    a + b
}

7. Typescript

Taking the drawbacks of JavaScript into consideration, the language of Typescript was developed by Microsoft in 2014. Typescript is trans-compiled to the JavaScript language and is better than the classic language.

Both Microsoft and Google were trying to develop a worthy successor to JavaScript. When Microsoft created Typescript, it was so good that Google cooperated with Microsoft to improve the programming language. 

Frameworks like Vue, React, and Angular have declared that they will use Typescript to develop future versions where JavaScript was earlier used. The language design of Typescript is very elegant and clean, which is a pleasure to work with.  

// Define a variable with a specific type
let greeting: string = "Hello, TypeScript!";

// Define a function with typed parameters and return value
function sayHello(name: string): string {
    return `Hello, ${name}!`;
}

// Call the function
const message = sayHello("Alice");
console.log(message); // Output: Hello, Alice!

// Define an interface to describe the shape of an object
interface Person {
    name: string;
    age: number;
}

// Create an object that adheres to the Person interface
const person: Person = {
    name: "Bob",
    age: 30,
};

// Define an array with a specific type of elements
const numbers: number[] = [1, 2, 3, 4, 5];

// Use a for...of loop to iterate through the array
for (const num of numbers) {
    console.log(num); // Output: 1, 2, 3, 4, 5
}

// Use optional and default parameters in a function
function greetPerson(name: string, greeting?: string = "Hello") {
    console.log(`${greeting}, ${name}!`);
}

greetPerson("Eve"); // Output: Hello, Eve!
greetPerson("Dave", "Hi"); // Output: Hi, Dave!
