I am stuck on this coding challenge Spinal Tap Case from freeCodeCamp. Essentially I don’t know how to get the last check to execute.
This is the last check:
spinalCase("AllThe-small Things") should return "all-the-small-things"
And this is my code:
function spinalCase(str) { var outputString, newstr, pattern1 = new RegExp(/[_s]/, 'g'), pattern2 = new RegExp(/(?=[A-Z])/, 'g'), stringTest1 = pattern1.test(str), stringTest2 = pattern2.test(str); if(stringTest1) { outputString = str.replace(pattern1, '-'); newstr = outputString.toLowerCase(); } else if(stringTest2) { str.split(/(?=[A-Z])/).join(' '); outputString = str.replace(pattern2, '-'); newstr = outputString.toLowerCase(); } else if (stringTest1 && stringTest2){ outputString = str.replace(pattern1, '-'); outputString = str.replace(pattern2, '-'); newstr = outputString.toLowerCase(); } return newstr; }
I do realize the last else if
condition should go first however I didn’t get the syntax right.
Thanks in advance!

Answer
Here is how I recommend doing it:
function sp(str) { var spinal = str.replace(/(?!^)([A-Z])/g, ' $1') .replace(/[_s]+(?=[a-zA-Z])/g, '-').toLowerCase(); return spinal }
as far as your code, you check for:
if test1
else if test2
, then else if test1 and test2
, the logic is not correct:
you could try to adding a !test2
or !test1
to the first if checks to get it working:
if (stringTest1 && !stringTest2)...
EDIT:
here is how you can get your code to fire in that last else if, I put a console.log in there to show you here:
function spinalCase(str) { var outputString, newstr, pattern1 = new RegExp(/[_s]/, 'g'), pattern2 = new RegExp(/(?=[A-Z])/, 'g'), stringTest1 = pattern1.test(str), stringTest2 = pattern2.test(str); if(stringTest1 && !stringTest2) { outputString = str.replace(pattern1, '-'); newstr = outputString.toLowerCase(); } else if(!stringTest1 && stringTest1) { str.split(/(?=[A-Z])/).join(' '); outputString = str.replace(pattern2, '-'); newstr = outputString.toLowerCase(); } else if (stringTest1 && stringTest2){ console.log('were in the last else!!!'); outputString = str.replace(pattern1, '-'); outputString = str.replace(pattern2, '-'); newstr = outputString.toLowerCase(); } return newstr; }
