Getting Things Wrong
Getting Things Wrong
So today, in a rather exciting bit of news, I got something wrong.
And that is exciting because I don't normally get things wrong. And that's not only because I'm good. It's also because I'm afraid to let go of the handrails sometimes. I'm afraid to take risks.
Today I took a risk on my JavaScript, and I got something completely wrong. I'm so glad that this was able to happen lol.
The biggest thing that I am trying to figure out is: WHERE did I go wrong? In my thinking - because I know where I went wrong in my code (and I have now fixed it since).
So what happened? What did I get wrong?
Magic-8 Ball
Magic 8-Ball is a classic exercise that is used by Codecademy when using 'if'/'else if'/'else' statements. I'm not sure if they use it with all other languages but I would imagine they do too - I have most definitely done it in Python.
Basically, in the JavaScript exercise, I first came up with this bit of code:
(Omg this is so cool btw I didn't know that I could do this!)
And then this is the correct code that I needed to do this i.e. to product a magic 8 ball with a random answer based on a random number:
So I got there in the end... but only after following the video.This is the incorrect code that I put initially
et userName = "Susanna"
userName ? console.log(`Hello, ${userName}!`) : console.log("Hello!");
const userQuestion = "Will I become a Software Engineer?"
console.log(`${userName}, your question is: ${userQuestion}`)
let randomNumber = Math.floor(Math.random() *11)
console.log(randomNumber);
(Omg this is so cool btw I didn't know that I could do this!)
And then this is the correct code that I needed to do this i.e. to product a magic 8 ball with a random answer based on a random number:
let eightBall = "";
switch(randomNumber) {
case(0):
eightBall = "It is certain";
break;
case(1):
eightBall = "It is decidedly so";
break;
case(2):
eightBall = "Reply hazy try again";
break;
case(3):
eightBall =' Cannot predict now';
break;
case(4):
eightBall = 'Do not count on it';
break;
case(5):
eightBall = 'My sources say no';
break;
case(6):
eightBall = 'Outlook not so good';
break;
case (7):
eightBall = 'Signs point to yes';
break;
case(8):
eightBall = 'It is written';
break;
case(9):
eightBall = 'It is meant to be';
break;
case(10):
eightBall = 'Follow your heart';
break;
}
console.log(eightBall)
console.log(`Your answer, ${userName}, is ${eightBall}`);
So I got there in the end... but only after following the video.
I was quite pleased with myself that I don't have to follow the whole video or anything... I just muted it and cross-checked the code.
This is the incorrect code that I put initially
let eightBall = "";
switch(eightBall) { case(0): console.log("It is certain"); break; case(1): console.log("It is decidedly so"); break; case(2): console.log('Reply hazy try again');eightBall = "Reply hazy try again"); break; case(3): console.log('Cannot predict now'); break; case(4): console.log('Do not count on it'); break; case(5): console.log('My sources say no'); break; case(6): console.log('Outlook not so good'); break; case (7): console.log('Signs point to yes'); break; case(8): console.log('It is written'); break; case(9): console.log('It is meant to be'); break; case(10): console.log('Follow your heart'); break;}
let eightBall = "";
switch(eightBall) {
case(0):
console.log("It is certain");
break;
case(1):
console.log("It is decidedly so");
break;
case(2):
console.log('Reply hazy try again');eightBall = "Reply hazy try again");
break;
case(3):
console.log('Cannot predict now');
break;
case(4):
console.log('Do not count on it');
break;
case(5):
console.log('My sources say no');
break;
case(6):
console.log('Outlook not so good');
break;
case (7):
console.log('Signs point to yes');
break;
case(8):
console.log('It is written');
break;
case(9):
console.log('It is meant to be');
break;
case(10):
console.log('Follow your heart');
break;
}
So what was my thought process and where did I go wrong with it initially?
I made two mistakes initially:- I made the variable in the Switch case eightBall and not randomNumber
- What was I thinking and why did I do that? I don't really understand myself
- I think, because I thought that I was writing text (i.e. ultimately outputting a string), I thought I had to put in a text-based (i.e. a string) variable as well
- Why didn't I make the link that once the number was randomised it would FILL THE EMPTY STRING WITH WHATEVER IT NEEDED TO BE?
- The other mistake I made was:
- I'd only seen the switch/case example used with console.log before
- So I'd incorrectly assumed that the example in the project had to be done in the way that I'd seen it done before
- Instead it was '=' that had to/could be used in this example
- How could I avoid making this mistake in future please? Thank you.
Just for fun, here is a picture of Venice Beach in LA... I'm listening to a song by Lana del Rey which is a play on words, but you'll have to look it up for yourself... Not something I'm sharing on here 😂😂
