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.

ascending() function in D3. js is a built-in comparator function for the natural order which accepts two parameters and computes their natural order. Parameters: This function accepts two parameters x, y whose natural order needs to be computed.
ascending (a, b)” is used? This command is comparator function that is used for a natural order, and can be used along with the built-in-array sort method to arrange elements in ascending order.
1 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.
Ascending order is the complete opposite of descending order - it is also known as increasing order of importance. Items are arranged from lowest to highest value. The order starts with the smallest value coming first and ends with the biggest value.
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]
The node.sort () function in D3.js is used to sort the children at each level of the given hierarchical data. The comparator function can be used to define the basis on which the sorting would be done. Parameters: This function accepts a single parameter as mentioned above and described below:
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]
