Nasalino:
Has anyone received the second assessment test ? the technical part that is supposed to come after the multiple choice

Afolabi6046:
thanks all... would do that and check back.... actually i used word= word. toLowerCase()....that worked fine with bracket(my editor)

eph12:

What i did was to pass a condition for if word is an empty space or not a string

Afolabi6046:
function isIsogram(word){

word = word.toLowerCase();

var i, j;

for ( i = 0; i<word.length; i += 1){

for ( j = i + 1; j<word.length; j += 1){

if ( word[i] == word[j] ){
return false;
}
}

}
return true;
}





.......................................guys that my code, tried your options, still not working

Afolabi6046:
function isIsogram(word){

word = word.toLowerCase();

var i, j;

for ( i = 0; i<word.length; i += 1){

for ( j = i + 1; j<word.length; j += 1){

if ( word[i] == word[j] ){
return false;
}
}

}
return true;
}

Hi, first of all starting a post with "still not working" doesn't help us debug a solution for you. Please provide a description of the error that you are getting so we can help you better especially for peeps who are just stumbling on this thread. Running the code on my editor throws no errors, So it is up to you to tell me what the exact nature of the problem is so I and others can help.

stevenakp:



the test cases have these calls to the function
isIsogram( )
isIsogram( " " )

you've been trying to convert a null value and an empty string to lowercase, which of course won't work.

try this.
1. write a condition to check if "word" is undefined (which take care of the null value passed to the function) or if "word" is lesser than or equal to zero (which takes care of the empty string passed to the function)

2. you should return "false" if any of this is true.

3. carry on with your algorithm.

eph12:

You should sort your word first so they are arranged alphabetically after converting to lower case.

Before converting to lower case and sorting, you should have something like this

if ( word !== string || word !== "" ){
return false;
}

Afolabi6046:
function isIsogram(word){

if ( word == "" || word <= 0 ){
return false;
}

word = word.toLowerCase();

var i, j;

for ( i = 0; i<word.length; i += 1){

for ( j = i + 1; j<word.length; j += 1){

if ( word[i] == word[j] ){
return false;
}
}

}
return true;
}





........................guys i ran this again, gave me the " TypeError: Cannot read property 'toLowerCase' of undefined" again
i think i'm doing something wrong

function isIsogram(word){

var newArray = word.split('');
var result = [];
var hash = new Object();
for(var i = 0; i < newArray.length; i++){
var element = newArray[i];
if(!hash[element]){
hash[element] = true;
result.push(element);
}
}
if(result.length !== newArray.length){
return false;
}else {
return true;
}
}
can anyone help. the code works fine in my text editor
but doesnt work in qualified.io
gives this error message:

TypeError: Cannot read property 'split' of undefined
