Glue Code

Glue code refers to small bits of code written to connect different software components, libraries, systems, or APIs that were not originally designed to work together. It's not responsible for the core functionality but rather for bridging gaps, handling conversions, adapting interfaces, or orchestrating data flow between parts of a system. Glue code is common in scripting, automation, and integrating legacy systems or third-party libraries.

Analogy: magine an international conference where people from different countries speak different languages. Each speaker (software component) has something important to say (core functionality), but they can’t understand each other directly. Glue code is like the translator. It doesn’t add new ideas to the discussion, but it enables communication by interpreting and rephrasing (I.E. ) converting Spanish to English, or summarizing a speech for clarity. Without the translator, each participant might talk past the others.
