Naming convention of callback in node.js

Question

Is there a naming convention for the name of the callback function you pass to async methods in node.js? I've seen a number of different names used and I generally pick a name that makes sense in the given context.

Has a convention emerged?

Answer 1

I think there are no general naming convention. I use a normal speaking name in camelCase. My co-worker prefers the Callback postfix like handleUserListCallback. My other co-worker prefers the Handler postfix and another prefers the __ (double underscore) prefix (yes he was a python believer).

For naming the variable: Name it clearly.

function fetch(parameter, callback) {}
function worker(parameter, done) {}
function job(parameter, finish) {}

Try to use an understandable naming. One that you can understand and other who tries to read or improve your code and be consequent.
