Creates a thread pool that takes a block and run it in parallel with different jobs and returns a list of the results

Write one function that is useful for you and others

How many times you have been looking for a function that does one
thing and you end up using a gem just for one function?

Here we'll fix that, consider rubyfunctions.com is your repository
for useful functions, you can get back to it any time

Depend on Ruby standard library and core library only

We all have seen the problem with too many dependencies, here we'll try to be as minimal as we can, we'll build off of ruby core and standard library only, making our functions as independent as possible, this means you'll be able to use it any project regardless of its framework

Show it to others and get feedback

Now that you have a useful repository of functions you have wrote, show it to other developers, your function maybe useful for other people, Also you will get feedback from other developers to improve your knowledge, And you'll have the chance to also give feedback to others and learn something new from their functions
