JavaScript

💪 Challenge yourself regularly

Training through different exercises and challenges is important because it will allow you to improve many areas of your skill set:

• Algorithms (don't expect incredible progression either 😟).
• Improve your execution speed (fluidity to write the code).
• Practice (and potentially discover) language features. Note that in this case it is important to synchronize the discovery with a desire to document yourself (articles, talks, ebook).
• Allow you to discover a significant part of our daily life and the difficulties we have to face.

I recommend that you regularly give yourself more or less intensive code sessions. It often happens to me to see beginners looking for a job taking "their time" only to complain after a few months that they are not making any progress 😑.

The following links will allow you to do a set of workshops and challenges:

• [Beginner] freecodecamp
• [Beginner] nodeschool
• [Beginner] JavaScript Algorithms Crash Course - Learn Algorithms & "Big O" from the Ground Up! - Learning fundamentals of algorithms.
• [Intermediate] jskatas
• [Intermediate] warriorjs - Code your path through dungeons.
• [Intermediate] “Build Your Own Array in Javascript!”

 

🏫 Nodeschool

If you're a beginner or new to the Nodeschool workshops, I'll walk you through the different choices available to you.

Note that you're going to need to get comfortable with command line instructions 😬 (this is a good opportunity to get started if you haven't yet).

⚠️ Some workshops are no longer maintained

Among the workshops I recommend (more or less in order):

• [Simple] JavaScripting
• Learnyounode
• [Discovery] How to npm
• Functional JavaScript
• [Discovery] Planet proto
• [Simple] Count to 6
• [Important] Promise it won't hurt
• Learn generators
• Bytewiser
• [Hard] Stream Adventure

 

Bradley challenges

Beware these challenges are very difficult (and also require Node.js and V8 knowledge).

• Day 1: Surviving the Freeze (Warmup)
• Day 2: Cleaning up the mess
• Day 3: Disappearing Act
• Day 4: Silent connection, holy connection
• Day 5: Are we done yet?
• Day 6: Is anybody listening?
• Day 7: Under the ice
• Day 8: Immaculate coercion
• Day 9: Bundlers Hate This
• Day 10: Back to Algorithms
• Day 11: The old switcheroo
• Day 12: You say goodbye, I say hello

 

🔎 The other websites

Various websites offering various challenges and exercises:

• CodingGame
• CodeWars
• Leetcode
• HackerRank (There are categories for Mathematics and Algo).

I don't necessarily have a recommendation for these (as far as I'm concerned, I don't necessarily like these sites).

 

🏆 Competitive programming

If some of you are highly motivated and want to get into code competitions (or math and algorithm solving is your thing ^^) well I recommend the following links:

• What is Competitive Programming?
• Competitive Programmer’s Handbook
• Starting Competitive Programming - Steps and Mistakes
• How to start Competitive Programming? For beginners!
• Fundamentals of algorithms
• Codeforces

This is a field that will require you to work very seriously on mathematics and to study the various existing structures and algorithms at length.

👀 Please note that my own goal is to climb the Codeforces ranking and to participate in several rounds in the coming years.
