nodeJS Write integer to buffer using buffer.writeInt16BE

Question

I want to ask, how to store a number (integer in JS) in buffer using buffer.writeInt16BE().

Assume I have a number such as

var a = 40000;

40000(10) = 9C40 (16)

how can I store 40000 in buffer of size of 2, so it looks something like:

<9c, 40>

You can't use buf.writeInt16BE() because 40000 is larger than 32768. However if you use buf.writeUInt16BE() you can write 40000 to the buffer just fine.

I am getting an error like: ReferenceError: writeUInt16BE is not defined

Those are methods available on the Buffer instance, not global functions.
