+## A stringified string
+
+This caused a bug that I've been solving for a few days:
+
+```js
+JSON.stringify('production') === 'production' // -> false
+```
+
+### 💡 Explanation:
+
+Let's see what `JSON.stringify` is returning:
+
+```js
+JSON.stringify('production') // -> '"production"'
+```
+
+It is actually a stringified string, so it's true:
+
+```js
+'"production"' === 'production' // -> false
+```
