Shim

A shim is an intermediate layer. It fills the gap between two things.

What's a shim?

A shim is a physical object inserted between two things when a gap exists. For example, a piece of paper, metal, or wood inserted under chair legs stops wobbling.

Examples of Shims

1. Docker Shim - Helps the Docker daemon control containers.
2. Python Shim - Helps you choose and use different Python versions.
3. Adapter Shim - Code that connects different API versions.
