/**

|
* 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
