Question

I wanted to know the difference between sort function and ascending function in d3.
I am looking for a way to rearrange the data in my table in ascending order of the column selected.

Thanks.

Answer 1

Array.sort() will sort the values alphabetically in ascending order. Array.sort(d3.ascending) will sort the values naturally in ascending order. The difference can be seen when you are sorting a list of numbers.

var a = [3,26,1,7];

console.log(a.sort());
// prints [1,26,3,7]

console.log(a.sort(d3.ascending));
// prints [1,3,7,26]
