Javascript Array Sort Numbers

At the heart of JavaScript array sorting is the Array.sort method. This built-in function allows you to sort the elements of an array in place, meaning it modifies the original array. However, this default behavior can lead to unexpected results when sorting numbers const numbers 10, 2, 5, 1, 30 numbers.sort console.lognumbers

Here are some common methods to Sort Numeric Array using JavaScript. Please note that the sort function by default considers number arrays same as an array of stings and sort by considering digits as characters. Using sort with a Comparison Function - Most Used

Sorting Numbers Correctly. To sort numbers correctly, we need to provide a comparison function to sort. This function determines the order by comparing pairs of elements and deciding their order based on the result. Syntax for Ascending Order array.sorta, b gt a - b Syntax for Descending Order array.sorta, b gt b - a

How To Sort Numbers Accurately in JavaScript. The sort method of JavaScript compares the elements of the array by converting them into strings and then comparing their Unicode code points. This can lead to unexpected results when sorting arrays of numbers, as seen in the example where 10, 5, and 80 are sorted as 10, 5, 80 instead of 5, 10, 80.

numbers.sorta, b gt a - b but if we're going to be sorting multiple arrays in this way, we probably want to declare a function and pass it into the sort instead like this const numberSorter a, b gt a - b numbers.sortnumberSorter Now we can pass numberSorter to any array's sort method to sort it numerically. Here's the array

Conclusion sort does sorting by only looking at the first index of the numbers.sort does not care if a whole number is bigger than another, it compares the value of the unicode of the digits, and if there are two equal unicode values, then it checks if there is a next digit and compares it as well. To sort correctly, you have to pass a compare function to sort like

If compareFn is not supplied, all non-undefined array elements are sorted by converting them to strings and comparing strings in UTF-16 code units order. For example, quotbananaquot comes before quotcherryquot. In a numeric sort, 9 comes before 80, but because numbers are converted to strings, quot80quot comes before quot9quot in the Unicode order.

When the sort function compares two values, it sends the values to the compare function, and sorts the values according to the returned negative, zero, positive value.. If the result is negative, a is sorted before b. If the result is positive, b is sorted before a. If the result is 0, no changes are done with the sort order of the two values.
