+### `objectGuards`
+
+Type: `Boolean`<br>
+Default: `false`
+
+When replacing dot-separated object properties like `process.env.NODE_ENV`, will also replace `typeof process` object guard
+checks against the objects with the string `"object"`.
+
+For example:
+
+```js
+replace({
+  values: {
+    'process.env.NODE_ENV': '"production"'
+  }
+});
+```
+
+```js
+// Input
+if (typeof process !== 'undefined' && process.env.NODE_ENV === 'production') {
+  console.log('production');
+}
+// Without `objectGuards`
+if (typeof process !== 'undefined' && 'production' === 'production') {
+  console.log('production');
+}
+// With `objectGuards`
+if ('object' !== 'undefined' && 'production' === 'production') {
+  console.log('production');
+}
+```
