'Cause I'm good in spirit, warm-bodied

Oh my goodness.

Today's blog post profiles one of the most beautiful songs in existence - "Grandfather please stand on the shoulders of my father while he's deep-sea fishing" - hey man - don't know it 'til you've tried it. Yes the title is weird. Yes it's long.

IT'S ALSO ONE OF THE MOST BEAUTIFUL SONGS THAT YOU HAVE EVER HEARD OR WILL EVER HEAR IN YOUR LIFE.

I CANNOT stop listening to it today.

How beautiful it is.



How much softness and gentleness.

Today's blog post is about state management

Why bother with state management?

State management is very important to software engineering. 

"Component-specific memory is called state". I am not 100% sure what this means. However this helps: "state is data that changes." So therefore: "when the state object changes, the component re-renders".

What this basically means is that:

When new data is available, the individual component(s) can be re-rendered. But the whole page doesn't have to reload. This is especially helpful for when you have bigger applications.

 When you have an app with multiple components, you have to think about how it is that the data, or state, flows between them.

State management "involves handling and manipulating the state of an application or system".

Having used state management before, what I understand it to be is this...

An event happens: a user clicks something, or something is loaded, or whatever. This triggers a change of state. 

The change of state then causes the component to re-render... and I guess to have a new state.

"State management provides a centralised location for storing and managing application state". This allows application programs to have "a single source of truth", I guess. This helps you to keep your data consistent. And it helps to avoid conflicts that may arise from having different conflicting pieces of state.

"Component-specific memory is called state". For smaller and mid-sized apps we might be able to use our own framework's tools for state management. 

But, apparently, as the app gets larger, it can be good to incorporate third part state management tools.

The Perks of State Management

Are you ready? Here we go...
  • Centralised Data Storage
  • Consistent User Interface
  • Data Sharing and Communication
  • Simplified Data Flow
  • Modularity and Reusability
  • State Persistence
  • Time Travel and Debugging
  • Scalability and Performance Optimisation
  • Integration with External Services
  • Predictable State Updates

Context

I have never heard of this term before, in this context (no pun intended... see what I did there?), but it's so cool. From my course: "passing props can become verbose and inconvenient when you need to pass some prop deeply through the tree or if many components need the same prop".

I will write more on this later. Thank you so much!

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as

Yosemite

Yosemite I'll never forget the first time I head the song Yosemite by Lana del Rey. I very nearly clicked away.  It was quite near the start of my Software Engineering journey, right near when I start learning the Front-End/Web Development. I was listening to Arcadia by LDR before, maybe twice, and then Blue Banisters came on. I nearly clicked away in the first 30 seconds but I forced myself to keep listening anyway.  I'll never forget how that song has made me feel. It became my song of 2022 even though I only discovered it in November. I can still listen to it every day and get that complete sense of wonder and of awe that I felt the first time that I heard it. That ending of the song is completely amazing, and it just completely just blows me away every time. "Withstanding all the time, changes, and seasons..." - LDR Concise Body Arrow Functions Why am I so bad at arrow functions? Whyyyyyyyyyyy?  Just kidding, I am beginning to get them. But why are they so hard? &

Two Lines of Thought, Makes Me Wonder What I'm Missing

Two Lines of Thought, Makes Me Wonder What I'm Missing "Lines of Bamboo, See What You Do To Me..." Bamboo by Elder Island is one of my ultimate 'becoming a Software Engineer songs'. (I prefer the original, but here is a great live version. ) There's a story behind this. I met a man named Mark. He was an SWE approaching retirement - he was down in my hometown with his wife, visiting. I won't go into the context of how we met, but it was a miracle. It was a complete miracle. It was just meant to be. We chatted for at least two hours and at the end of the conversation he said to me "All the best of luck with your new career". I couldn't believe what he'd just said - I hadn't even committed to it yet! A few weeks later, I did, though. After I walked out of that cafe where I had been sitting and talking to Mark and his wife though, I felt like - even though I didn't "feel ready" yet - Mark had predicted something that I didn&
