The split function is creating redundant values

Please help me with this issue I am facing while trying to split a string using split(). It's causing duplicate values which is frustrating. Can someone please assist me?

The string I need to split is a comma-separated response from a database, and here is the echo: 

echo $Title1 . ',' . $link. ','.$value. ','.'number'.','.'$' .',';

My code snippet is as follows:

function handleResponse(response2){
        var str = response2;
        var str_array = response2.split(',');
    }

I'm seeing duplicates in the console log when I print str_array:

0: "Butter cauliflower & paneer"
1: "https://link1.com"
2: "4"
3: "friends5"
4: "$"
5: "Butter cauliflower & paneer"
6: "https://link1.com"
7: "4"
8: "friends5"
9: "$"
10: "Butter cauliflower and coconut sambal"
11: "https://link2.com"
12: "3"
13: "friends5"
14: "$"
15: "Butter cauliflower and coconut sambal"
16: "https://link2.com"
17: "3"
18: "friends5"
19: "$"

Here is the actual value of response2:

Butter cauliflower & paneer,https://link1.com,4,friends5,$,Butter cauliflower & paneer,https://link2.com,4,friends5,$,Butter cauliflower and coconut sambal,https://link3.com,3,friends5,$,Butter cauliflower and coconut sambal,https://link4.com,3,friends5,$,Creamy vegetarian pumpkin curry,https://link5.com,5,friends5,$,

Can you help me understand why `split()` is behaving this way?

Answer №1

Dealing with this issue drove me to the point of madness. Consider incorporating this Within the function

let uniqueValues = new Set([]);
var strData = response2.split(',');
for(var i = 0;i < strData.length - 1;i++){
  uniqueValues.add(strData[i]);
}
console.log(uniqueValues)

It would have been more helpful if you included the string being split, aiding others in finding solutions faster.

If this solution doesn't yield results, feel free to leave a comment for further assistance.
