In programming, function signatures represent the declaration of a function—typically including the function name and its parameters. Function signatures are the entry points to any block of reusable code, helping developers understand how a function can be called and what arguments it requires.

This extractor tool parses your code and extracts the signatures of functions defined in your program. Whether you're working in Python or JavaScript, you can quickly obtain a summary of your function declarations. This is especially useful for:

• Documentation: Generate a quick reference list of available functions.
• Code Review: Identify the structure of your code during reviews.
• Learning: Understand how functions are defined in different languages.

Example:

For Python:

def greet(name):
    print("Hello, " + name + "!")
    

Extracted signature:

greet(name)
    

For JavaScript:

function add(a, b) {
    return a + b;
}
    

Extracted signature:

add(a, b)
    

Understanding function signatures is critical in all coding disciplines. They serve as blueprints for how functions operate and interact within a codebase. This tool is intended to improve code readability and help document software, especially in larger projects where a quick overview of available functionality is invaluable.
