Hi, guys!

Challenge yourself with our latest missions:

The first mission is called "Split List" and here your task is to split a given array into two arrays.

splitList([1, 2, 3, 4, 5, 6]) == [[1, 2, 3], [4, 5, 6]]
splitList([1, 2, 3]) == [[1, 2], [3]]

The second one is "Replace Last" mission where you have to replace the last element with the first one.

replaceLast([2, 3, 4, 1]) == [1, 2, 3, 4]
replaceLast([1]) == [1]

The third one is "Replace First" and here you must replace the first element with the last one.

replaceFirst([1, 2, 3, 4]) == [2, 3, 4, 1]
replaceFirst([1]) == [1]

The fourth mission is called "Compress List" where you need to "compress" a given array so that there's only one element instead of the equal ones.

conpress([
 5, 5, 5,
 4, 5, 6,
 6, 5, 5,
 7, 8, 0,
 0]) == [5, 4, 5, 6, 5, 7, 8, 0]
conpress([1, 1, 1, 1, 2, 2, 2, 1, 1, 1]) == [1, 2, 1]

Highlights from the JS world:
• You just have to go over the 4th edition of JavaScript Rising Stars! You’ll find the projects that have been added on Github over the last 12 months and got the most traction in 2019.
• Don’t forget to check out the roundup of the most relevant and impactful publications relating to the JS world from JavaScript Weekly.
• Useful information for those who want to know how to move their project from JavaScript to TypeScript. You’ll find a lot of information on why it might be a good idea and great advices on how it can be practically done. Maybe we should apply this to the CheckiO code runner...hmm :)

Our congratulations to the winner of December 2019 - bartosh.leurc78 - you are totally Awesome and we are very glad to have you here with us!

Little by little CheckiO is starting to grow and now we have an opportunity to add a new Content-Hero and the Mission-Creation-Monster into our team part-time. Together we’ll work on CheckiO and Empire of Code. Are you interested? Then fill in this simple form so we could find out a little bit more about you and how we can get in touch.
