Odyssey : noun

a series of experiences that give knowledge or understanding to someone

an intellectual or spiritual quest

Hi folks, thanks for tuning in! This is a kinda catch-up post as I have been a bad boy and not blogged weekly as I intended - blame it on the mind-blowing-bending stuff we have learned ๐Ÿคฏ and the need to rest my brain!

I am now calling this series my odyssey because that better encapsulates the path I am on - a bit more epic that a mere functional journey, I think.

So to orient ourselves this is about weeks 2-4 of my odyssey, following week 1 which was an introduction week. This is called the fundamentals block which covers the building blocks of JavaScript which we need to understand to progress to more higher-level and useful ways of using JavaScript. I'm a big fan of fundamentals-first learning.

I'm going to list the topics we have covered and give them a rating based on how well I think I grasped the topic:

๐Ÿคฏ I get what it is about but would struggle to teach it or give a good example

๐Ÿ˜ I get it and could probably explain it

๐Ÿค“ Love it! totally makes sense

Here we go:

  • Testing with Jest ๐Ÿค“
  • Array Methods ๐Ÿค“
  • Higher order functions ๐Ÿ˜
  • Scope ๐Ÿค“
  • Function hoisting ๐Ÿ˜
  • Difference between a variable's value versus its reference ๐Ÿค“
  • 'Pure functions' ๐Ÿ˜
  • Testing side effects of functions with no return value with jest mock functions ๐Ÿคฏ
  • Closure ๐Ÿ˜
  • Destructuring ๐Ÿค“
  • Higher order functions
  • Recursion ๐Ÿคฏ
  • Object Orientated Programming ๐Ÿค“
  • Factory functions and this keyword ๐Ÿค“
  • Constructor functions and instance methods ๐Ÿค“
  • Class syntax ๐Ÿค“
  • Callback functions ๐Ÿ˜
  • HTTP requests with Axios ๐Ÿค“
  • Promises and .then() and .catch() ๐Ÿ˜

Wow! what a list - we covered so much in 3 weeks. It was not all plain sailing but we will be getting a lot more practice so I am confident the majority will sink in, in time.

Bring on the back end!
