+### hasFlags
+
+Check if the current process's arguments contain the specified flags.
+
+Use `Array.every()` and `Array.includes()` to check if `process.argv` contains all the specified flags.
+Use a regular expression to test if the specified flags are prefixed with `-` or `--` and prefix them accordingly.
+
+```js
+const hasFlags = (...flags) =>
+  flags.every(flag => process.argv.includes(/^-{1,2}/.test(flag) ? flag : '--' + flag));
