What is difference between exports.function_name = code_for_function and export function_name = code_for_function?

Issue

I am new to typescript and I am working on a firebase project where I want to use cloud functions for updating some values in cloud firestore. I wanted to know what's the difference between exports.function_name = code_for_function and export function_name = code_for_function, so that I can use them appropriately.

I saw exports.function_name being used in firebase documentation and export function_name being used in a YouTube video by firebase. So I wanted to know the difference and use cases.

I did read a similar question though it was regarding modules and not functions so I wasn't sure if the same is applicable here.

Solution

exports.XXX is the older CommonJS (CJS) export syntax.

export XXX is the currently dominant MJS standard.

I'd recommend using the latter.
