+### Equality comparison
+
+Comparing two dates in JavaScript using the loose or strict equality operators (`==` or `===`) is not recommended for most cases. Equality operators compare the `Date` object references, resulting in `false`, even if the date values are the same:
+
+```js
+const a = new Date(2022, 01, 10);
+const b = new Date(2022, 01, 10);
+
+a === b; // false
+```
+
+### Date.prototype.getTime()
+
+One way to compare two `Date` values is using the `Date.prototype.getTime()` method. This method returns a number indicating the number of milliseconds elapsed since the Unix Epoch:
+
+```js
+const a = new Date(2022, 01, 10);
+const b = new Date(2022, 01, 10);
+
+a.getTime() === b.getTime(); // true
+```
+
+### Other methods
+
+As mentioned before, `Date.prototype.getTime()` is one way to compare two `Date` values. It's not the only one way to compare them. Other options are the following:
+
+- `Date.prototype.toISOString()`
+- `Date.prototype.toUTCString()`
+- `Date.prototype.toLocaleDateString()` provided you use the same locale
+
+All of these methods produce consistent results, but we still recommend `Date.prototype.getTime()` due to its simplicity.
