海外TECH	DEV Community	Ultimate guide to sorting in Javascript and Typescript	https://dev.to/maciekgrzybek/ultimate-guide-to-sorting-in-javascript-and-typescript-4al9	Ultimate guide to sorting in Javascript and TypescriptBackground vector created by freepik www freepik comThis post was originally published on Leocode Blog IntroductionSurely in your coder software engineer developer professional keyboard basher career you came across a situation when you had to sort some kind of data or UI elements In most cases it s pretty straightforward but sometimes it can be a real pain In this article I ll try to explain how sorting works in the TypeScript and JavaScript world show you some real life examples and speak briefly about few popular libraries that can make sorting much easier Basic sortingLet s start with the most basic example and sort the array of strings const words Tango Zulu Bravo Lima words sort gt Bravo Lima Tango Zulu That s the simplest way to alphabetically sort an array of strings in ascending order What if we want to sort it from Z to A instead We need to pass a compare function const words Tango Zulu Bravo Lima words sort a b gt if b gt a return if b lt a return return gt Zulu Tango Lima Bravo This might look confusing at first been there but trust me it s actually making a lot of sense when you get it How the compare function worksThe compare function takes two arguments the current element and the next element It has to return a number that will define how the elements have to be sorted The general rule is if you return a number greater than element b will go to the beginning will receive a lower index number than element a if you return a number smaller than element a will go to the beginning will receive a lower index number than b if you return elements will remain at the same positionWith a simple number sorting we can even go a step further and simplify the compare method Ascending orderconst arr arr sort a b gt a b gt Descending orderconst arr arr sort a b gt b a gt Let s analyze the first two array elements comparison in the first example we do which evaluates to meaning element b should be before element a should be before in the second example we do which evaluates to meaning element a should be before element b should be before Then the sort method continues that for other numbers How exactly That depends on the browser As it turns out different browsers are using different algorithms to do that The API and the output are the same but under the hood they are sorting things in a slightly different manner If you want proof try the code below in Firefox and Chrome consoles and look at what s being returned it s not the same const words Tango Zulu Bravo Lima words sort a b gt console log Comparing a to b if b gt a return if b lt a return return If you want to dig even deeper check out this great explanation of different sorting algorithms TIPWorth having in mind sort is a mutable method which means it mutates the original array If you want to create a new array you can spread it and then sort it like this const words Tango Zulu Bravo Lima word sort Sorting with localeCompare methodIn previous examples we simply compared the strings and return the correct value to sort the strings in the array But there s another awesome way to do that plus it gives us additional superpowers I m talking about the localeCompare method What is it you ask Similar to examples before the function will return a number as a result of comparing the strings but it allows us to take the locale into consideration This is especially useful with languages that have special characters as they might have a different position in the alphabet Let s see some examples so it can all make more sense const words Tango Zulu Bravo Lima words sort a b gt a localeCompare b en gt Bravo Lima Tango Zulu Like I ve mentioned before the localeCompare return a numeric value so if a is before b in the alphabet it yields a negative value If b is before a it yields a positive value If they are the same it yields And we already know what does that mean for the sort method from the How the compare function works section But where are the superpowers you ask Let s take a look LocaleIf you are dealing with multiple languages in your app website it s important to pass the locale of the current language when you use sorting as some characters have a different position in the alphabet ö localeCompare z de returns a negative value in German ösorts before z ö localeCompare z sv returns a positive value in Swedish ösorts after z OptionslocaleCompare has also a third argument which is options There are a few of them but I ll show you two in my opinion most needed on a daily basis If you want to read more about them all I highly recommend the MDN and Tech on the net CasingYou can pass a caseFirst property to the options If you set it up as upper it will sort the uppercase words first when they are starting with the same letter If you pass lower it will sort the lowercase ones first const words Tango tango Bravo lima Lima words sort a b gt a localeCompare b en caseFirst upper gt Bravo Lima lima Tango tango words sort a b gt a localeCompare b en caseFirst lower gt Bravo lima Lima tango Tango Numeric valuesLet s say we want to sort the numeric strings if we won t pass the numeric true property they will be treated as strings and sorted like them will go before because is smaller than Check the examples below for a better understanding const words words sort a b gt a localeCompare b en gt words sort a b gt a localeCompare b en numeric true gt Real life examplesWe ve covered the theory which I hope will give you a better understanding of how sorting works now let s focus on real life examples I want to show you a few that will use just the native sort method and also a few that will use external libraries like lodash Let s go Sorting an array of objectsLet s say we have an array of objects each object will represent one dog and we want to alphabetically sort these objects by the breed property Let s see how we can do that Define the interface for our objectsinterface Dog breed string name string const dogs Dog breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos Sort based on breed property We don t have to explicitly type a and b arguments Typescipt will infer them from the dogs arraydogs sort a b gt if b breed lt a breed return if b breed gt a breed return return gt breed Bulldog name Thanos breed German Shepard name Rex breed Spaniel name Marley As you can see this is very similar to regular string sorting the only difference is that we are comparing specific properties of the objects TIPIt all depends on your preferences and probably your team standards but you can make the sorting function even shorter dogs sort a b gt b breed lt a breed b breed gt a breed Sorting based on different valuesSo we covered that but what if we ll have two bulldogs on our list We can sort them by breed first and then by name const dogs breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos breed Bulldog name Atreus Fist sort based on breed then if they are the same sort by name propertydogs sort a b gt if b breed lt a breed return if b breed gt a breed return else if b name lt a name return if b name gt a name return return gt breed Bulldog name Atreus breed Bulldog name Thanos breed German Shepard name Rex breed Spaniel name Marley As you can see we just add another branch in here if the compared values are the same we add another else path that handles comparing another property on the object name in this case TIPSometimes your sorting functions might get fairly complicated so it makes sense to extract them to their own methods and pass them to sort Define the interface for our objectsinterface Dog breed string name string It s a good idea to pass the types to arguments otherwise TS will treat them as type of any const sortDogsByBreedAndName a Dog b Dog gt if b breed lt a breed return if b breed gt a breed return else if b name lt a name return if b name gt a name return return dogs sort sortDogsByBreedAndName Sorting based on another arrayGetting back to our beloved dogs imagine we want to sort them by breed but not alphabetically Let s say we have a specific list of breeds that needs to be used as a reference for the sorting logic Take a look below as it might be easier to understand with the code example This array shows the order of sorting the dogs Spaniel should be first and German Shepard should be lastconst breedsOrder Spaniel Pug Bulldog Poodle German Shepard const dogs breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos breed Pug name Bean breed Poodle name Axel dogs sort a b gt breedsOrder indexOf a breed breedsOrder indexOf b breed gt breed Spaniel name Marley breed Pug name Bean breed Bulldog name Thanos breed Poodle name Axel breed German Shepard name Rex What happened here The array indexOf method returns a number position of the passed argument in the array In this situation if we compare the index of German Shepard and Spaniel we will receive which means that Spaniel should go first in our sorting method External librariesApart from your vanilla JS TS solutions there are lots of external libraries that expose a nice API to makes sorting easier Below I will show you examples from two of them lodash and fast sort lodashLodash is a very popular JavaScript utility library It has all kind of various methods that helps a lot with you daily developer tasks It also lets you use few sorting helper functions sortByThis method allows you to sort arrays of objects The output is exactly the same as in the Sorting based on the different values section before As a first argument you pass the array to sort and the second one is an array of object properties that we want to sort by in the example below sort first by breed then by name if breeds are the same import sortBy from lodash const dogs breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos breed Bulldog name Atreus sortBy dogs breed name gt breed Bulldog name Atreus breed Bulldog name Thanos breed German Shepard name Rex breed Spaniel name Marley orderByThis method is almost identical to sortBy except that it allows specifying the sort orders of the iterates So if we want to sort by breed in ascending manner but then by name in descending one we can do something like this import orderBy from lodash const dogs breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos breed Bulldog name Atreus orderBy dogs breed name asc desc gt breed Bulldog name Thanos breed Bulldog name Atreus breed German Shepard name Rex breed Spaniel name Marley fast sortThis is and easy to use and flexible sorting library with TypeScript support It has a little bit different approach than lodash when it comes to the API Let s see how we can solve the same sorting problem as we had before const dogs breed German Shepard name Rex breed Spaniel name Marley breed Bulldog name Thanos breed Bulldog name Atreus Sort ascending by breed then by namesort dogs asc dog gt dog breed dog gt dog name gt breed Bulldog name Atreus breed Bulldog name Thanos breed German Shepard name Rex breed Spaniel name Marley Sort ascending by breed then descending by namesort dogs by asc dog gt dog breed desc dog gt dog name gt breed Bulldog name Thanos breed Bulldog name Atreus breed German Shepard name Rex breed Spaniel name Marley Both of the mentioned libraries have of course much more options and possibilities Also there are plenty of other libraries that solve the same or similar problems just to name a few match sorter sort array or relevancy I encourage you to check their documentation and have a play trust me sometimes they can be a live saver SummaryI hope this article
