+✅ Fix grammar and add validation
+
+**The comment contains a grammatical error ("an unwanted features" should be "unwanted features"). Additionally, consider adding validation to ensure disableFeatures is an array before calling join() to prevent runtime errors.**
+
+[lib/chrome.js [323-324]](https://github.com/gnh1201/welsonjs/pull/276/files#diff-868ee66369a322a75a321ede18241bfb18f199a9e5bb5371d4d049f0af14f598R323-R324)
+
+```diff
+-// disable an unwanted features
+-cmd.push("--disable-features=" + this.disableFeatures.join(','));
++// disable unwanted features
++if (Array.isArray(this.disableFeatures) && this.disableFeatures.length > 0) {
++    cmd.push("--disable-features=" + this.disableFeatures.join(','));
++}
+```
+
+
+
+Suggestion importance[1-10]: 6
+
+__
+
+Why: The suggestion correctly identifies a minor grammatical error in the comment. More importantly, it adds validation to check if `this.disableFeatures` is a non-empty array before processing it. This is a good defensive programming practice that prevents potential runtime errors and avoids passing an empty `--disable-features=` argument.
