there is actually no need to save into variables the functions in our answers to these exercises, as we're not asked to then use them as parameters in higher order functions, so we can use a function expression, rather than a function declaration (plus, especially with the concise arrow syntax, we can use functions diretly as argumemts in other functions, or define and call them at the same time as an IIFE, eg. ((n)=> {console.log(n=5);}10); that logs 15)

great, I agree, your code should be short and fast at the same time.

why?

Not sure if this should be best practice

This solution does not work for something like " (space) 3.5 (space) "

Thanks!!

I thought I was doing something dumb using the replace method 3 times.

I'm just curious as to why this isn't the "best practice" it's this the "best" way to break the code down?

RegExp. See MDN.
