Heyyyyyy! It's the start of a work week but we're already 3 days into our challenge week. Let's do this!
⏰ You can Catch Up in no time!
We're on day 3 of this week's challenges which build upon each other.
Feel free to catch up:
and then head back over here!
I've also added all of this month's challenges to a series here on my blog - hope that helps!
⭐ Array Week
This week our challenges all deal with Arrays! Their purpose is to store a collection of things under a single reference name, but the way they are set up and used in JavaScript is a little different from other programming languages. If you're coming from a different language, be sure to check out what's different! While working on our challenges, feel free to use JavaScript's built-in Array methods.
🏆 The Challenge - Day 3
This week we'll be working with arrays toward a final puzzling result on Friday when we combine our daily functions. Your solutions should be built to work within any given daily constraints.
Today's challenge is a bit of a tangent, but I think it's pretty powerful. It's inspired by my favorite Codewars kata ever, Moving Zeros To The End. This is my favorite kata because the first time I did it, my approach was so convoluted compared to the top-voted solution, which was a thing of beautiful simplicity. I think the moment I saw that solution something clicked for me and I realized the power of the built-in Javascript methods.
Today I'd like you to write a function that:
- takes in a given array of strings and move any entries containing the letter 'a' to the front
- then move any remaining entries that have over 3 characters to the back
- please preserve the relative order of entries within their given category
Example:
myArr = ['hi', 'hello', 'howdy', 'hola', 'hej', 'hallo', 'heyyy']
// move things around
=> ['hola', 'hallo', 'hi', 'hej', 'hello', 'howdy', 'heyyy']
Have fun!
Wait, What's Huntober?
Leon Noel's 100Devs are spending October preparing for the job hunt. Anyone who has already broken into a tech career knows that the application and interview process can be grueling! The current cohort has progressed this year all the way from basic HTML files to hosted full-stack applications with authentication and databases.
This month they'll continue to build, but will also work on data structures & algorithms, networking and interview skills, and solving code challenges.
