Correction

Here is what's right.

Arrow function expressions can be written in different ways depending on the number of parameters and the body.

However, one never has to use the keyword function before the list of parameters.

Origin

Where could this misconception come from?

If one knows about traditional anonymous functions, their syntax prescribes the function keyword. As arrow functions are often used as a replacement for traditional anonymous functions, students might think that the same function keyword is required also for arrow functions.
