What does the rc stand for in the names of configuration files?

Question

Many tools in the modern JavaScript ecosystem name their configuration files ending in the letters rc. For example:

ES Lint -> .eslintrc.json

npm -> .npmrc.json

yarn -> .yarnrc

I know that these are configuration files.

The c most likely stands for configuration. What is the r in rc?
