@maxadams100 if you wanted to assign 5 to a var, i, would you say
var i; 5?

(Your string itself is good.)

see ya

@ednor

Who plays golf here ?

Keon Samuel

@keonsam

how long does it take to get a programming job?

kumquatfelafel

@kumquatfelafel

depends on the job

Ednor

@ednor

Golf Code challenge is completely stranger to me, if it was soccer, I'd understand in the seconds

kumquatfelafel

@kumquatfelafel

couldn't tell ya much more than that. Generally speaking, you can get a bit of an idea if your qualified by look at ... whatsitscalled (long day).

Ednor

@ednor

I am completely lost

Keon Samuel

@keonsam

yes that was a hard one to understand.

Diego Mayer

@Chrono79

@ednor compare strokes against the first column, return the second column, use if/else

kumquatfelafel

@kumquatfelafel

@keonsam job description! That's the word! :p

@keonsam nah. So I'm probably not the right one to talk to. ;)

@tiger500

convertToF(0) should return a number
convertToF(-30) should return a value of -22
convertToF(-10) should return a value of 14
convertToF(0) should return a value of 32
convertToF(20) should return a value of 68
convertToF(30) should return a value of 86
i need help

kumquatfelafel

@kumquatfelafel

@tiger500 post your code.

tiger500

@tiger500

@kumquatfelafel function convertToF(celsius) {
var fahrenheit;
// Only change code below this line

// Only change code above this line
return fahrenheit;
}

// Change the inputs below to test your code
convertToF(30);

kumquatfelafel

@kumquatfelafel

@tiger500 Did you try doing what @saifsmailbox98 said?

tiger500

@tiger500

yeah when i get the 2nd correct i get the 3rd one wrong @kumquatfelafel

Ednor

@ednor

@Chrono79 what about Strokes = Par, does that mean Par = 0 ?

kumquatfelafel

@kumquatfelafel

@ednor When strokes === par, you return "Par". for example

Diego Mayer

@Chrono79

@ednor no, and use == or === to compare when not specified, = is used to assign values
capitalization matters

kumquatfelafel

@kumquatfelafel

@tiger500 Let me see what you tried to do with saif. Maybe we can figure out what went wrong.

tiger500

@tiger500

function convertToF(celsius) {
var fahrenheit=0;

// Only change code below this line
fahrenheit=(-30+8);
fahrenheit=(-10+24);

// Only change code above this line
return fahrenheit;
}

// Change the inputs below to test your code
convertToF(30);

Ednor

@ednor

@Chrono79 what about Strokes = Par, does that mean Par = 0 ?
There is column where Par has any value

tiger500

@tiger500

@kumquatfelafel function convertToF(celsius) {
var fahrenheit=0;

// Only change code below this line
fahrenheit=(-30+8);
fahrenheit=(-10+24);

// Only change code above this line
return fahrenheit;
}

// Change the inputs below to test your code
convertToF(30);

Diego Mayer

@Chrono79

@ednor

@ednor When strokes === par, you return "Par". for example

Strokes        Return
1        "Hole-in-one!"
<= par - 2        "Eagle" //you compare strokes against par - 2 here, using <=
par - 1        "Birdie"
par        "Par"
par + 1        "Bogey"
par + 2        "Double Bogey"
= par + 3        "Go Home!"

kumquatfelafel

@kumquatfelafel

@tiger500 alright. Well you're not using the conversion formula here. You're just hardcoding values. You need to use the formula. So what's the formula to convert celsius to fahrenheit?

tiger500

@tiger500

@kumquatfelafel celsius9/5+2

Ednor

@ednor

@Chrono79, in this challenge, I must use if ... return; else if (*n) ... return; and else ... return;

kumquatfelafel

@kumquatfelafel

@tiger500 the formula we use to convert fahrenheit to celsius is Fº = Cº * 9/5 + 32.

Diego Mayer

@Chrono79

@ednor yes, all the if/else you need to address all cases

kumquatfelafel

@kumquatfelafel

@tiger500 do you have a variable that represents the temperature in Fº in your code?

Ednor

@ednor

@Chrono79 ,here is what i've tried, but failed


function golfScore(par, strokes) {
  // Only change code below this line

  if (par > 1) {
    return "Hole-in-one";
  } else if (par <= -2) {
    return "Eagle";
  } else if (par <= -1) {
    return "Birdie";
  } else if (par >= 1) {
    return "Par";
  } else if (par >= 1) {
    return "Bogey";
  } else if (par >= 2) {
    return "Double Bogey";
  } else if (par >= 3) {
    return "Go Home!";
  }
  else {
  return "Change Me";
  }
  // Only change code above this line
}

// Change these values to test
golfScore(5, 4);

@harryrf

Any idea what I'm still doing wrong here? https://codepen.io/harryrf3/pen/EXVWdv?editors=1010

My button changes from fahrenheit to celsius, but not back

Diego Mayer

@Chrono79

@ednor where is strokes there?

Ednor

@ednor

@ednor where is strokes there?
Euh !!!

tiger500

@tiger500

@kumquatfelafel no

kumquatfelafel

@kumquatfelafel

@tiger500 you don't see a variable you could use to store the temperature in ºF?

Ednor

@ednor

@Chrono79, so instead of using par as variable, it should be strokes, right ?

kumquatfelafel

@kumquatfelafel

@ednor both par and strokes are important.

Diego Mayer

@Chrono79

@ednor par and strokes are your function parameters, you have to use both (not in all cases)
strokes is needed in all your if conditions, compare it against the values of the table's first column

tiger500

@tiger500

@kumquatfelafel fahrenheit

kumquatfelafel

@kumquatfelafel

@tiger500 yep

@tiger500 how about for ºC?

Ednor

@ednor

@Chrono79, @kumquatfelafel, I am COMPLETELY lost

tiger500

@tiger500

@kumquatfelafel Celsius

Diego Mayer

@Chrono79

@ednor

if (strokes == 1) {
  return "Hole-in-one!"; // <- the string must be exactly what they wrote
