RajTo remove the comma from an array's last element, call the replace() method.
let array = ['value1', 'value2', 'value3', 'value4', 'value5,'];
let last_index = array.length-1;
let last_value = array[last_index].replace(',', '');
array[last_index] = last_value;
console.log(array);
//Output
['value1', 'value2', 'value3', 'value4', 'value5']
- Find the last element from an array using length.
array.length-1; - Replace comma using replace method and filter new value
array[last_index].replace(',', ''); - Push new value at last element index
array[last_index] = last_value;
Output will be
//Output
['value1', 'value2', 'value3', 'value4', 'value5']
