How can we specify default values for function parameters in PHP?
In PHP, default values for function parameters can be specified using the assignment operator (=) in the function declaration. This allows the function to have default values for parameters if no value is provided when the function is called. To specify a default value for a parameter, you simply assign a value to the parameter

How do you define a custom function in JavaScript?
A custom function in JavaScript is a user-defined function that allows developers to create their own reusable blocks of code to perform specific tasks. Defining a custom function involves declaring the function name, specifying the parameters it accepts (if any), and writing the code block that defines the function's behavior. To define a custom function

What is type hinting and how can it be used to specify the expected types of function parameters?
Type hinting in Python is a feature introduced in Python 3.5 that allows developers to specify the expected types of function parameters and return values. It provides a way to add type annotations to the function signatures, making the code more readable and self-explanatory. Type hinting does not enforce any runtime type checking, but it

What are default values for function parameters and how can they be specified?
Default values for function parameters in Python allow us to assign a default value to a parameter if no argument is provided during the function call. This feature provides flexibility and allows us to define functions that can be called with different sets of arguments. In Python, default values for function parameters are specified in

What is the purpose of type annotations in Python function parameters?
Type annotations in Python function parameters serve the purpose of providing information about the expected data type of the arguments passed to a function. They enhance the readability, maintainability, and reliability of code by explicitly specifying the types of input parameters. This feature was introduced in Python 3.5 through the use of the "typing" module,
