How to Sort an Array in JavaScript

When working with large quantities and volumes of data, you may find it difficult to manage the data. But thanks to technology, the task has been made significantly simpler. One of the tools of data management and arrangement is JavaScirpt. phone applicationsJavaScript has emerged as one of the most dynamic and useful computer programming language used universally. The tool is standardized by the ECMAScript language and is most commonly used as a portion of browsers, game development, as well as desktop and mobile applications. It is also used in a number of other platforms such as site-specific browsers, PDF documents, desktop widgets and so forth. As a programming tool, JavaScript can be of good use when sorting data.

Sorting data allows your data to be more organized in a sensible manner. For instance, you can arrange texts in alphabetic order or the reverse and numbers in descending or ascending order. What this does is simplify your job by not having you do it by hand. Furthermore, the sort() function in JavaScript allows you to get the lowest and highest values. By default, the sort() method is programmed to sort the values of data as strings in ascending and alphabetical order. The sort() method is supported in all the browsers such as Firefox, Chrome, Safari, Internet Explorer, and Opera. This is pretty cool considering the amount of data to be processed. So how do you do it?

First off, an an associative array is the most popular sort of array used which is also sometimes referred to a hash or map structure. It is simply a set of value pairs stored in association with its own key.

Sorting an array in JavaScript involves plugging in the data you need and manually programming formulaentering the sorting formula which will then be applied to the data and in turn, sort it in the order you want. Though sometimes this function in and of itself is not sufficient in displaying correct data, optional parameters can be used to define the sort order. Without perimeters such as the compareFunction, the array is simply set and sorted according to the characters’ Unicode point value which is sometimes not sufficient to supply data sorting that makes sense.

For example, when sorting (Cherry, apples) without a compareFunction will result in (Cherry, apples) instead of (apples, Cherry). arr.sort([compareFunction]) is the code for the compareFunction which will sort the data correctly according to alphabetical order as (apples, Cherry). This also applies in the arrangement of numbers. The sort() function would value and sort numbers according to the first digit. So automatically, arranging 5, 12, 9, 80 will result in (12,5,80,90). However, using the compareFunction allows the numbers to be arranged according to their numerical value instead of just the first number.

This method can be applied to significantly larger volumes of data which can help in cutting back the time it would take to sort the data one by one manually. JavaScript allows this task to be completed expediently and with minimal errors, granting you time savings and some fun in your programming venture.
