Ruby Ruby Foundations Blocks Examples

Why so you add a number *= 2 line in the block and not explain why it didn't change the array? thanks

The example of block shows array with 5 numbers, in the number block you add a number *2 line which doesn't seem to apply to any part of the array, yet there's no explanation about why the line was added...

The line was added to show you that it does not influence the original array and to show that if you apply that change AFTER printing, you will not se that change, because it's temporary and local. You should experiment with this code on your own to understand what is going on. For example add the puts line after the *= 2 line and see what happens.
