A glue language is like a special kind of glue that helps different computer programs talk to each other. You know how you sometimes need to use different toys together to make a bigger and more awesome toy? Well, computer programs work kind of like that too! The only problem is, sometimes they don't automatically understand or work well with each other.
That's where a glue language comes in. It's like a translator between different programs. It helps them understand each other's language and work together smoothly. It makes it possible for programs that couldn't normally interact with each other, to share information and work together on a bigger project.
So, just like glue, a glue language is an important ingredient to make sure things work smoothly and stick together!
