Dividing Code with Functions

🔑 Functions are used to break down large code into smaller, modular pieces.

👥 There are two types of functions: user-defined functions and built-in functions.

💻 Functions in Python start with 'def' and have a name and optional parameters.

🔑 Functions require parameters to be executed successfully.

💡 The number of parameters in a function can vary depending on its purpose.

🖨️ Functions can be used to print specific numbers in a code.

🔧 Functions are used to simplify and streamline code by avoiding repetitive writing and instead calling the function by name.

📏 Functions can be used to create reusable code for calculating the area of a rectangle, where the length and width are provided as parameters.

⏩ The 'return' statement in a function is used to return a value, allowing the function to store and provide a specific result when called.

🔑 The 'function' keyword is used to define a function in JavaScript.

💡 Functions can take parameters and return a value.

📝 The 'return' keyword is used to specify the value that the function will return.
