Could it be a potential issue with array sorting in Chrome and IE?

My array sorting script works perfectly on Firefox, however, Chrome and IE are giving me an unordered array.

var arr = ["2017-02-17",
"2017-02-17",
"2017-02-16",
"2017-02-15",
"2017-02-16",
"2017-02-15",
"2017-02-14",
"2017-02-16",
"2017-02-17",
"2017-02-17",
"2017-02-13"];
arr.sort(function(a, b) {return a>b;});
console.log(arr);

Could this issue be a bug in Chrome/IE or did I overlook something? It seems unlikely that Chrome and IE, which have different JS engines, would both have the same problem.

It's recommended to convert dates from strings to Date objects for accurate comparison.

String comparison may lead to issues due to varying date formats. For example, yyyy-m-d can cause unexpected results.

When comparing strings, 2017-1-12 may be considered greater than 2017-08-17.

var dates = ["2017-02-17", "2017-02-17", "2017-02-16", "2017-02-15", "2017-02-16", "2017-02-15", "2017-02-14", "2017-02-16", "2017-02-17", "2017-02-17", "2017-02-7", "2017-02-13"];

dates.sort(function(a, b) {
  var date1 = new Date(a);
  var date2 = new Date(b);
  return +date1 - +date2;
})

console.log(dates)

Remember: As mentioned by @User123, if your input is always in ISO format, string comparison may suffice (refer to @AnotherUser's answer). However, if there's a chance of receiving dates in other formats, comparing Date Objects is a safer approach.

Answer №2

Consider using the appropriate comparison method for Array#sort and returning it as a value instead of a boolean, which can remove negative values as needed.

If you are working with ISO 6801 date strings, String#localeCompare can be utilized for comparison.

var arr = ["2017-02-17", "2017-02-17", "2017-02-16", "2017-02-15", "2017-02-16", "2017-02-15", "2017-02-14", "2017-02-16", "2017-02-17", "2017-02-17", "2017-02-13"];

arr.sort(function(a, b) {
    return a.localeCompare(b);
});
console.log(arr);

If Unicode code points are not a concern, Array#sort can still be used.

The sort() method sorts the elements of an array in place and returns the array. The sort is not necessarily stable. The default sort order is according to string Unicode code points.

without compareFunction

var arr = ["2017-02-17", "2017-02-17", "2017-02-16", "2017-02-15", "2017-02-16", "2017-02-15", "2017-02-14", "2017-02-16", "2017-02-17", "2017-02-17", "2017-02-13"];

arr.sort();
console.log(arr);

Answer №3

To sort the array, you can simply use the sort method without specifying a callback function.

arr.sort();


var arr = ["2017-02-17",
"2017-02-17",
"2017-02-16",
"2017-02-15",
"2017-02-16",
"2017-02-15",
"2017-02-14",
"2017-02-16",
"2017-02-17",
"2017-02-17",
"2017-02-13"];
arr.sort();
console.log(arr);
