CodePudding user response：
There is a data without lastname.

you are trying to get fullname on line 17 and split it by space
Line 17: var pairs = temp[1].split(/ (.*)/s);
so when it parsing the data without last name, the pairs variable will return array value with only one element inside.
Line 20: personsObj.id = temp[0];
Line 21: personsObj.firstName = pairs[0].trim();
Line 22: personsObj.lastName = pairs[1].trim(); // Error triggered, because `pairs` variable only return one element
Line 23: personsObj.gender = temp[2].trim();
Solution, you can check the pairs[1] first (you can use ternary operator), so you can change the code on line 22 with code below
Line 22: personsObj.lastName = pairs[1] ? pairs[1].trim() : '';
so, when there is no last name presented it will replaced to empty string ''
CodePudding user response：
There is no last name in this line:
2343434340,Nagy,male
So personsObj.lastName = pairs[1].trim(); will throw an error since pairs[1] is undefined.
