[SOLVED] Count And Remove Consecutive Duplicates From An Array
I want to delete the consecutive duplicate values from the array and count unique consecutive values. But I am not getting expected result. Please check and help. Current Output: [aa, bb, aa, cc, cc, dd, ee, cc] [1, 1, 1, 2, 2, 2, 1, 1] Expected Output: [aa, bb, aa, cc, dd, ee, cc] [1, 1, 1, 4, 2, 1, 1] https://code.sololearn.com/W69Q4IqextAQ/?ref=app

Mohammed No. It should merge only consecutive (where next element is same as current) elements.
See description for expected result.

In if part, increment count and dont push any. In else part push all and reset count..
edit :
wordArray = [ "aa", "bb", "aa", "cc", "cc", "cc", "cc", "dd", "dd", "ee", "cc" ]
newArray = [];
countArray = [];
for (i = 0, count=1; i<wordArray.length; i++) {
//..removed
if(wordArray[i] === wordArray[i + 1]) {
count = count + 1;
//..removed
}
else {
newArray.push(wordArray[i]);
countArray.push(count);
count = 1;
}
}
console.log(newArray)
console.log(countArray)

Do you mean the expected result of the first array is:
[aa, bb, cc, dd, ee] ?
