Why so much Randomness 🤔 !

Question

Hi, Have a look at his ,

https://github.com/getify/You-Dont-Know-JS/blob/2nd-ed/get-started/apB.md#practicing-prototypes

Can you see the reel.spin() - that's to spin the reel, alright!

The if the statement is for spinning the reel( choosing other this.position randomly) for the first time

But but, what's the point of assigning

this.position

to

( this.position + 100 + randMax(100)) % this.symbols.length;

Does it add more randomness to the spinning or is it something else ?

Answer 1

Doesn't makes sense ,outcome is still random(about more randomness ,can't say that) like with the first method ,the other method only do one thing ,includes the position 7 as well
