+* Checks if the given value is a Buffer instance.
+*
+* This function tests whether the provided value is an instance of Buffer.
+* It returns `true` if the value is a Buffer, and `false` otherwise.
+*
+* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `Buffer`.
+*
+* @param x - The value to check if it is a Buffer.
+* @returns Returns `true` if `x` is a Buffer, else `false`.
+*
+* @example
+* const buffer = Buffer.from("test");
+* console.log(isBuffer(buffer)); // true
+*
+* const notBuffer = "not a buffer";
+* console.log(isBuffer(notBuffer)); // false
