I'll bend beneath my weight

Few songs express my love for software engineering as much as "The Place I Want To Be" by Badly Drawn Boy and Saint Saviour. They express my love and my passion for software engineering - for something that I just found or that just found me and I dropped everything I had in my life for it gladly and willingly - and followed it blindly.

Just a few points on async

JavaScript is a single threaded programming language. 

The execution of the code occurs in a single, sequential order. Therefore, only one set of instructions can be executed at a time. 

That's funny. 

It sounds a bit like me and my neurodiversity.

One call stack

"In a single-threaded language, there is only one call stack". What is a call stack?

"A data structure that keeps track of the sequence of function calls in a program."

"Each function call is added to the call stack, and when the function returns, it is removed from the call stack".

Promises

From my course: 

"A Promise is used to handle an asynchronous operation in JavaScript as they are objects that represent a value that may not be available yet but will be resolved eventually".

A Promise has three possible states:
  • Pending
  • Fulfilled
  • Rejected
Let's take a closer look:
  • Pending = awaiting resolution
  • Fulfilled = successful asynchronous operation
  • Rejected = unsuccessful asynchronous operation

.then

This is a method. It is called on a Promise object.

It takes two arguments:
  • A success callback
  • An error callback

When I get sad I stop being sad and I look at the offshore wind farms instead


And that's it really

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&
