How to remove trailing commas from the last element of an array using JavaScript?

To 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']
