+
+JavaScript's **`.MAX_VALUE`** represents the largest positive numeric value that can be represented using the `Number` type before it overflows to `Infinity`.
+
+## Syntax
+
+```pseudo
+Number.MAX_VALUE;
+```
+
+**Parameters:**
+
+None: `.MAX_VALUE` is a static property of the Number object.
+
+**Return value:**
+
+A number representing the largest positive finite value JavaScript can represent using the `Number` type (approximately 1.7976931348623157e+308).
+
+## Example
+
+This example shows what happens when a number exceeds `.MAX_VALUE`:
+
+```js
+const large = Number.MAX_VALUE * 2;
+console.log(large);
+```
+
+The output generated by this code is:
+
+```shell
+Infinity
+```
+
+Multiplying beyond `.MAX_VALUE` causes the result to overflow to `Infinity`, since JavaScript can't represent values larger than this limit.
+
+## Codebyte Example
+
+This codebyte example checks whether a large number is still within JavaScript's numeric limit:
+
+```codebyte/javascript
+const safe = 1e+307;
+console.log(safe < Number.MAX_VALUE);
+```
