Now Back Onto The Loops

But first, here's a picture of the forest near my house in Luxembourg. 


I like to go walking here and it's just SO BEAUTIFUL.

do... while Statements

So I did these yesterday and I did them way too fast and I would like to go over them one more time please - thanks!!! But the premise is simple: 

  • A do...while loop does something ONCE - this is GUARANTEED - and this is the DO BIT.
    • THEN, AFTER IT HAS DONE THE LOOP ONCE - IT CHECKS THE CONDITION AT THE END. 
      • OR, IT EVALUATES IT!!! 
    • THEN, IF THE CONDITION IS TRUE THEN IT REPEATS THE LOOP
      • FOR HOWEVER MANY TIMES
        • FOR HOWEVER LONG IT IS THAT THE CONDITION IS TRUE. 
  • Wow, thank you so, so much! Wow, this is amazing! Thank you!!! 
    • At this point I am just thanking whoever it was that invented this -
    • this is SO COOL!

Sample syntax of a do... while statement 

let stringCounter = ' ';

let i = 0;

do {
  stringCounter = stringCounter + i;
  i++;
}while ( i < 5);

console.log(stringCounter)

The output of this, as I expected it to be, is 01234, although I don't understand why it prints on a line and with no spaces, as opposed to with other loops, which often seem to print one element per line, one by one.

Quoting Chat GPT

Now, we all know that I have been BANNED from using Chat GPT - at least when it comes to finding solutions to coding problems. But I haven't been banned from using it for analysing code - in fact that's what my boss told me it's good for (at my level anyway).

Chat GPT has some surprisingly good quotes about do...while loops:

Chat says about a do...while loop:

"This type of loop will always execute the code block at least once, and then repeat it as long as the condition in the 'while' statement IS TRUE".

Some more examples of do... while loops:

Someone on discord gave me this code:

const examples = [];
do {
  const newExample = await askForNewExample();
  if (newExample) {
    examples.push(newExample);
  }
} while (examples.length < 6);

I'm not 100% sure if it actually works, BUT it is a nice example of what a do...while loop could look like/and do in some other shape/or form. 

OMG I am such a mug... here is the example from my course

Because, let's say, this was a pretty good one, actually... and it worked.

const cupsOfSugarNeeded = 5;

let cupsAdded = 0;

do {
  cupsAdded++;
  console.log(cupsAdded);
} while (cupsAdded < cupsOfSugarNeeded);

I love this example, it's so cuuuuuuuuuuuuuuuuuuuuute! It's all about baking a cake.

And what the course said was that they love cakes and they have a sweet tooth and that they wanted to add in a cup of sugar NO MATTER WHAT omg (... that is the do... part in the loop). 

And okay maybe they didn't say that they loved cakes... maybe I just added that bit in. 

The break keyword

Here is the example of the break keyword from the Codecademy course because my brain is too tired to come up with anything else.

for (let i = 0; i < 99; i++) {
  if (i < 2) {
    break;
  }
  console.log('Banana.');
}

console.log('Orange you glad I broke out the loop!');

What the code is actually doing here:

Two parts of the code are inside of the actual for loop. - The bit that checks if i <2 and then breaks if it does - and then the bit that console.log()s 'Banana'. 

Basically, if the if condition is true, then the for loop breaks.

Looping Through Arrays

Okay so I just wanted to go over this one again because it was the one thing I didn't feel like I had quite grasped when I went 

Ahh I see. So the main thing here to remember - as always - is the .length property. 

I got this wrong an an example that I sent to by boss on Monday, but we went over it together, so I really should have this clear in my head by now. 💮

The for...of Loop

"As well as with arrays, for...of loops also work with strings, sets, and other array-like objects.
              
Therefore, you should opt for a standard for loop if you need to access the indices or need finer control to determine what elements you want to loop over."

*

"The for...of loop does not change in structure regardless of the iterable object used". 

I.e. the for...of loop is the same regardless of whether it is used for an array or a string, for example.

*

"for...of has the advantage of setting up most of your loop parameters for you, but sometimes it is necessary to reclaim some control of how iteration is managed. One way of doing this is using JS's break and continue statements". 

The break and continue statements

Again, we're still in for...of loops here.

break

Th break statement stops the loop right there an then if the loop encounters a certain value. This "can be used to jump out of a loop". 

Example:

const greatSongs = ['Stairway To Heaven', 'Question It All', 'Beginning To See The Light', 'There's A Light'];

for (const song of greatSongs) {
  if (song === 'Beginning To See The Light') {
    break;
  }
  console.log(song);
}

The output will be:

Stairway To Heaven
Question It All

Makes sense?

continue

The continue statement essentially skips "one iteration of the loop". One iteration of the loop, one iteration of the loop.

So an example is:

const thingsILove = ['Software Engineering', 'Coding', 'JavaScript', 'Singing', 'Codecademy'];

for (const love of thingsILove) {
  if (love === 'Singing') {
    continue;
  }
  console.log(love);
}

Because I love all of these things but one of them is the odd one out! The expected output would be:

Software Engineering
Coding
JavaScript
Codecademy

When not to use a for...of loop

Well, for a start...

When ITERATING THROUGH AN ARRAY in REVERSE.

for...of Loop Practice Challenges

Arrrrrrgh I can get the to WORK... but I don't UNDERSTAND how they work!!!

WAIT SO THERE ARE for...in loops as well? 

I am struggling here. There's a lot to take in at once.

I can barely even understand for...of loops. I spent so long revising all of those expressions... and now they want to just take them away. 

But only at the right times!!! It's so confusing.

What on earth even is a for...in loop as well?

What I have to say to myself is this: is this really all urgent right now? 

Can I come back to this in a few days time?

Is it all urgent?

Written This Morning: Plan for the Day

(This is something I wrote at the start of the day. I will come back to it later for now. 🤗)

I am feeling a bit lost and disorientated and overwhelmed today so I would like to map out my plans. As I have a pretty empty day i.e. one that I need to structure all by myself for self study.

So the plan for me is this

Morning

  • Read over Codecademy's informational on for loops and over loops stuff. Write up all and any notes I have.
  • Revise over
    • While loops
    • Do...while statements
    • Breaks
  • Revise over my whale song project that I built yesterday
    • Because I built it very quickly

Maybe share with team.

Afternoon

Start on objects - I also have a 1:1 with a mentor so depending on how loops go I may just talk to them about those - 

Or hopefully, and alternatively, perhaps, I can 

  • Finish the above
  • Start on objects before
  • And maybe I can come into my 1:1 already with some questions on objects. 😊

Later: I was way too ambitious omg - or maybe, I just really needed to revise loops (and for...of loops).

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&
