imagine if it asks for nano seconds or an unit even smaller, the top solution is better cause it won't be much of a problem to edit compared to this one

Don't know why this is so far below the && solution.
But I am happy I finally got one of the top answers on my Kata.

Very concise with the ternary. Good work!

There are people who can't do math, so...

Why isn't this solution best practice? It seems so simple and straight forward.

Thank you @St3f4n i understand it now i'm a beginner in JS thats why it seems weird for me.

It's shorthand for Number(), so it's just a simple converting to a number.

can somebody explain to me why in the code there is the plus sign in the beggining of the code in my code i used parseFloat but this plus in the beggining i didnt understand .

666

I see, then these websites are wrong, when they state that the let keyword is part of the ES6 and newer:

Sorry, just a little confused.

no, this is not ES6 dependent

This will only work for ES6, right?

Additionally, I didn't even think about putting a conditional test as the property value in an object! Very succinct and novel.

This is great! I used your code if you don't mind in my blog and tried to explain how it works.
