What are the key differences between Python and JavaScript syntax?

Python and JavaScript have distinct syntax styles. Python uses indentation to define code blocks, while JavaScript uses curly braces. Additionally, Python is dynamically typed, meaning you don't need to declare variable types, whereas JavaScript requires the use of 'var', 'let', or 'const'.

Can you give examples of how to define a function in both languages?

Sure! In Python, you define a function using the 'def' keyword:

def my_function():
    print('Hello from Python!')

In JavaScript, you can define a function like this:

function myFunction() {
    console.log('Hello from JavaScript!');
}

What about variable declaration?

In Python, you simply assign a value to a variable without declaring its type:

my_variable = 10

In JavaScript, you need to use 'var', 'let', or 'const':

let myVariable = 10;

Are there any other major differences I should know about?

Yes! Another major difference is how they handle asynchronous programming. JavaScript uses callbacks and promises, while Python has async/await syntax for handling asynchronous operations.
