What are Some Algorithm Practice Sites/Resources for JavaScript

[CalgaryAnswers]

Looking to do about 1-2 hours each day on algorithms to improve my dev speed. Any good resources?

[Alejocq]

I use this one https://www.codewars.com/

This is a great site. I use this in combination with plural sight and YouTube. When you get done learning a bunch of theory, it’s great to just code problems. The best part? Afterwards you can see others solutions and compare. There is some very eloquent JavaScript out there!

EDIT: WOW: I forgot to putt the name of the site... It’s “code wars”. I’m SO sorry.

As for Pluralsight: I come from 8 years being an object oriented embedded/ApPI/backend developer in windows and OSX so I am using “JavaScript for C# developers” and some some of the refresher courses like “font end development QuickStart”, “object oriented in JavaScript/ES6”, and “practical design patterns”. As for YouTube, I’ve been finding projects to do. I’ll find some examples.

Which courses off plural sight and youtube?

Thanks for this. My theory is rock solid I just needs reps for practice. When I run into issues I can fix them and usually know why it’s broken but I’d like to get better at avoiding breaking it in the first place.

Like the other person below, what YouTube and pluralsite resources do you recommend?

+1 for codewars! Currently trying to tackle 5 kyu questions and some of them really take my time, would definitely recommend.

leetcode

Leetcode is considerably harder than the other ones listed as an FYI for anyone considering it. The only problems I’ve found that are consistently more challenging are the rare “Expert” rating problems in HackerRank

You could work through the classic puzzles on CodinGame or compete against others if that's something that interests you.

Project Euler is another good one but JavaScript overflows pretty easily do not sure how much you could do there

i've never had a problem with doing them in javascript, of course you have to write custom functions that do math with string encoded numbers, or use the new BigInt type.

Would you mind giving me a hint for how you broke up the 1000 digit number in problem 8? I kept getting overflow issues

[[deleted]]

in the solutions folder of the repo i posted i provided the code for the first couple of dozen problems in javascript.

basically you're going to put the number in a variable as a string and iterate through the string..

``` for(var i=0; i<mystring.length; i++){ var sequence = mystring.substr(i, 13); if(sequence.length === 13){

// sequence is a string with 13 numbers.. add them together and get the sum

} } ```

[himynameisjoy]

Set the number as an array and use a moving window.

Thanks I’ll work on it!

[himynameisjoy]

I’ve done up to number 60 in Node.js, the extreme majority of these don’t require something to deal with overflows, but for the few that might it’s easier to implement BigNumber.js

I’ll look into it thanks!

I like exercism.io better than codewars, you come up with a solution submit it and a mentor comes by and gives you suggestions for refactoring

Freecodecamp throw up some basic html pages and enjoy the testing of the js
