Detect if the current environment is a Continuous Integration (CI) environment. is-ci offers a simple boolean check, returning true if the code is running on a common CI platform like Travis CI, CircleCI, GitHub Actions, or Jenkins. This is helpful for conditionally enabling or disabling features or behaviors that are specific to CI systems, such as verbose logging or automatic deployments. Simplify your workflow by easily identifying CI environments.
