How to fetch last value in the for loop using javascript?

Question

enter image description here

 var new_data = $.parseJSON(data);
 for (var j = 0; j < new_data.all_soa_details.length; j++) {
 var td7_contact = new_data.all_soa_details[j].bal; //100,200,200,50 . here i need to fecth 50 only
 let td77_contact = Math.abs(td7_contact);
 }

i am getting values 100, 200,40,60, 50.. Here i need to fetch 50 becoz its last valuje in the for loop .How to get this last value?

• Barmar: td7_contact isn't an array, why are you trying to iterate over it?
• Barmar: Can you show what data looks like? What is the value of the .bal property?
• Nimw Ns: yes its not an array.. but i want to fetch the last value as 50 ..Need to show balance after the loop
• Barmar: Is it a comma-separated string?
• Barmar: After the loop is done, td7_contact contains the last value.

Answer 1

new_data.all_soa_details[new_data.all_soa_details.length - 1].bal

should give you the expected result

Answer 2

Try this out, I just wrote a code for you..

let new_data = {
 all_soa_details: [
 {
 bal: [1, 2, 3, 45],
 },
 {
 bal: [1, 2, 3, 45],
 },
 ],
 };
 for (var j = 0; j < new_data.all_soa_details.length; j++) {
 var td7_contact = new_data.all_soa_details[j].bal; //100,200,200,50 . here i need to fecth 50 only
 let td77_contact = Math.abs(td7_contact);
 }
 // let findOut;
 // for (const lastIter of td7_contact) {
 // findOut = lastIter; //Last iteration value stored in each iteration.
 // }
 // console.log(findOut);
 // Main code ....
 console.log(
 new_data.all_soa_details[0].bal[
 new_data.all_soa_details[0].bal.length - 1
 ]
 );
 for (let i = 0; i < new_data.all_soa_details.length; i++) {
 console.log(
 new_data.all_soa_details[i].bal[
 new_data.all_soa_details[i].bal.length - 1
 ]
 );
 }

• Barmar: I don't think bal is an array.
• Barmar: @NimwNs You already said that above, you don't have to tell me twice.
