+
+In JavaScript, the **`fromCharCode()`** method creates a string by converting one or more UTF-16 code units (numeric values) into their corresponding characters. This method is often applied in scenarios involving character encoding, dynamic character generation, or simple encryption tasks. It is particularly useful for converting ASCII or Unicode values into readable text.
+
+## Syntax
+
+```pseudo
+String.fromCharCode(num1, num2, ..., numN)
+```
+
+**Parameters:**
+
+- `num1, num2, ..., numN` (Number): One or more integer values representing UTF-16 code units. Each number should be between 0 and 65535.
+
+**Return value:**
+
+Returns a string composed of characters corresponding to the provided UTF-16 code units.
+
+## Example
+
+The following code converts a sequence of UTF-16 code units into the string "Liany❤️" and logs it to the console:
+
+```js
+const number = String.fromCharCode(76, 105, 97, 110, 121, 10084, 65039);
+console.log(number);
+```
+
+The output of this code is:
+
+```shell
+Liany❤️
+```
+
+## Codebyte Example
+
+Run the following code to understand the working of the `fromCharCode()` method:
+
+```codebyte/javascript
+const secret = String.fromCharCode(
+  76, 111, 110, 103, 32, 108, 105, 118, 101, 32, 116, 104, 101, 32, 107, 105, 116, 116, 105, 101, 115
+);
+console.log(secret);
+```
