so the point of the arrow function in basically just because making the arrow is slightly less to type?

then the word function in a regular expression function? is that the only difference? am i missing something here?

There's a concise form that is much more compact. But there are also a number of functional differences between conventional and arrow functions, one particularly notable one is how they use the keyword "this".

For more details on all the differences, see this MDN page on Arrow function expressions.

And they are used as callback functions.
