The main function of a scripting language is to automate tasks and enhance the functionality of software applications. Scripting languages, such as JavaScript, Python, or Ruby, allow developers to write code that can manipulate data, perform calculations, or control application behavior dynamically. Unlike compiled languages, scripting languages are typically interpreted at runtime, making them ideal for rapid prototyping and development. They empower developers to create versatile and efficient solutions, enabling quicker response to changes and improved user experience within software environments.
