I have this array of pairs in JS :

var my_array = [['line_1','2'],['line_2','0'],['line_3','5'],['line_4',''],['line_5','4'],]

For now to sort it by second item I am using :

var my_sorted_array =my_array.sort((a, b) => a[1] - b[1])

But I would like to put the blank/empty and null values to the end.

Expected result :

[['line_1','2'],['line_5','4'],['line_3','5'],['line_2','0']['line_4','']]

Thanks
