海外TECH	DEV Community	Would anyone care for some Javascript curry? (Tutorial)	https://dev.to/miketalbot/javascript-curry-anyone-3l34	Would anyone care for some Javascript curry Tutorial Functional programming and currying are topics that have some of us staring at the wall and saying something like there is no spoon whilst sadly shaking our heads Yet we know that there is a powerful tool sitting there so we struggle on in a bid for mastery of the dark arts I started life as a C C programmer and over the years I ve made money in a whole bunch of languages but functional programming proved to be a very different path I ve come some way down this track so I thought I d share my understanding and one of the utilities I ve made along the way BasicsLet s start with the basics If you have a function function calculate a b c return a b c You could rewrite it as const calculate a gt b gt c gt a b cYou d call the first one like this console log calculate And you d call the second one like this console log calculate The second implementation is a function which creates a function which creates a function to calculate the answer this is moving from The Matrix into Inception huh We converted the original using Javascript arrow functions and basically replacing a with a gt The first function returns takes the parameter a and returns a function for the parameter b Thanks to closures the final function has access to all of the previous parameters and so can complete its work The benefit of this is code reuse Until the last function we are basically running a factory to create functions that have the already supplied parameters baked in const calculateTheAnswer calculate for let i i lt i console log calculateTheAnswer i Now in this case you might be saying oh nice seems ok can t see the point though The strength comes when you start making more complicated things by passing functions around as parameters and composing solutions out of multiple functions Lets take a look CurryingFor the sake of this article I want an example that is simple yet not only multiplying two numbers together So I ve come up with one that involves multiplying and taking away Seriously though I hope the that it proves to give a practical perspective Ok so imagine we are building a website for a manufacturing company and we ve been tasked with displaying the weights of the companies UberStorage containers when made in a variety of sizes and materials Some smart bloke has provided us with access to a library function to calculate the weight of a unit function weightOfHollowBox edgeThickness heightInM widthInM depthInM densityInCm return heightInM widthInM depthInM densityInCm heightInM edgeThickness widthInM edgeThickness depthInM edgeThickness densityInCm See multiplying and taking away We don t want to mess with this as it isn t our code and might change but we can rely on the contract of the parameters being passed Our website is going to need to display lots of different output like this So we are going to have to iterate over dimensions and materials and produce some output We want to write the minimum code possible so we think of functional programming and curry Firstly we could make up a wrapper to that function const getHollowBoxWeight edgeThickness gt heightInM gt widthInM gt depthInM gt densityInCm gt weightOfHollowBox edgeThickness heightInM widthInM depthInM densityInCm But immediately we start to see some problems we have to call the functions in the right order and given our problem we need to think hard to see if we can make up a perfect order that maximises reuse Should we put density first That s a property of the material edgeThickness is standard for most of our products so we could put that first Etc etc What about the last parameter we probably want that to be the thing we iterate over but we are iterating both material and dimensions Hmmmm You might be fine writing a few versions of the wrapper function you might be fine throwing the towel in saying I ll just call weightOfHollowBox but there is another option Use a curry maker to convert the weightOfHollowBox to a curried function Simple curry not too many ingredientsOk so a simple curry function would take weightOfHollowBox as a parameter and return a function that can be called with a number of the arguments If we have completed all of them calculate the weight otherwise return a function that needs the remaining parameters Such a wrapper would look a bit like this const currySimple fn provided gt fn length is the number of parameters before the first one with a default value const length fn length Return a function that takes parameters return params gt Combine any parameters we had before with the new ones const all provided params If we have enough parameters call the fn otherwise return a new function that knows about the already passed params if all length gt length return fn all else return curry fn all If we call this on weightOfHollowBox we end up with a function that is a little more flexible than the hand written one const getWeightOfBox currySimple weightOfHollowBox All of these combinations work console log getWeightOfBox console log getWeightOfBox We can pass all of the parameters or any subset and it works in those cases This does not solve our parameter ordering issue We would dearly love a version of this that allowed us to miss out interim parameters and have a function for just those e g const getWeightOfBox curry weightOfHollowBox const varyByWidth getWeightOfBox MISSING console log varyByWidth JalfreziWarning there follows some much more advanced code to create this new curry function you don t need to understand it if you don t want to You could use this implementation or one of the many others out there without needing to get the inner workings If you want to see how this is done read on otherwise skip to the next section Ok lets cook up some proper curry First we need something that uniquely identifies a missing parameter const MISSING Symbol Missing With that in our toolbox we can go ahead and write our new curry function const curry fn missingParameters Array from length fn length i gt i parameters gt return params gt Keeps a track of the values we haven t supplied yet const missing missingParameters Keeps a track of the values we have supplied const values parameters Loop through the new parameters let scan for let parameter of params If it is missing move on if parameter MISSING scan continue Update the value and the missing list values missing scan values length parameter missing splice scan Call the function when we have enough params if missing length lt return fn values else Curry again Yes please return curry fn missing values Right let s start with those parameters The fn is the function to be curried the next two we use when recursing through in the case that we need to make another intermediate function rather than call fn missingParameters defaults to the numbers n where n is the number of parameters required by fn In other words when we first call it it is the indices of all of the parameters required for fn The next parameter is an empty array that we will populate and pass down should we need to The function we return takes any number of parameters We take a copy of the missing indices and the existing parameters and then we iterate over the new parameters If the parameter value is MISSING we move on to the next missing index When it isn t MISSING we populate the correct index in the values array which we allow to take more parameters than the function as that s how you deal with any that might have be defaulted Having populated the array we remove the missing index Once that s all done if the missing list is empty then we call the function passing it the values otherwise we recurse Note we never set the length of the array Javascript arrays automatically set their length to the maximum value if you write to an index in them That s it this function allows us to create a range of templates Example Web SiteNow we have a way of wrapping weightOfHollowBox we can start to put together the elements of our web page Firstly lets code up the thing that shows the weight of an item and its material We can see that the inner item is something based on iterating over the material We have this definition of materials const materials name Aluminium density name Steel density name Oak density So we write a curried function to render the item that takes a way to calculate the weight a function we will create from our curried weightOfHollowBox and a material const material weightInKg gt material gt lt ListItem key material name gt lt ListItemText primary material name secondary lt span gt weightInKg material density toFixed tons lt span gt gt lt ListItem gt This will display any material so long as we can give it a function to calculate the weight that requires the density Let me show you a simple way this could now be used function Simple const weightInKg curriedWeight return lt List className App gt materials map material weightInKg lt List gt We create a weight calculator looking for density and then we call our material function passing that which returns a function that needs a material this will be passed by the materials map We are going to do something fancier for the site though A block for all materialsWe want to output a list of materials so let s write a function for that const materialBlock header gt weightCalculator gt materials gt dimension gt lt Fragment key dimension gt header dimension materials map material weightCalculator dimension lt Fragment gt This curried function allows us to supply something that will write a header then given a weight calculator a list of materials and a dimension it will output all of the materials for that group That s a bit trickier let s see how we might use that in an isolated way const ShowByHeight gt const heights const weightCalculator curriedWeight MISSING const outputter materialBlock height gt lt ListSubheader gt m wide x height m tall lt ListSubheader gt weightCalculator materials return lt List className App gt heights map outputter lt List gt Here we have a React component that knows the standard heights of our units It creates a weight calculator that still requires height and density and then provides materialBlock with a header to put over it For the site we can get better code reuse though const ShowBy weightCalculator gt header gt values gt lt List className App gt values map materialBlock header weightCalculator materials lt List gt We create a reusable ShowBy function which we can then use to create versions for our standard widths and heights const widths const heights const ByWidth gt ShowBy curriedWeight MISSING width gt lt ListSubheader gt m tall x width m wide lt ListSubheader gt widths const ByHeight gt ShowBy curriedWeight MISSING height gt lt ListSubheader gt m wide x height m tall lt ListSubheader gt heights Pulling it togetherOur final function is used to put the parts together const Advanced gt lt Box gt lt Box mb gt lt Card gt lt CardHeader title By Width gt lt CardContent gt lt ByWidth gt lt CardContent gt lt Card gt lt Box gt lt Box mb gt lt Card gt lt CardHeader title By Height gt lt CardContent gt lt ByHeight gt lt CardContent gt lt Card gt lt Box gt lt Box gt Here s the whole thing ConclusionI hope this has been an interesting look at currying in Javascript The area of functional programming is very deep and we ve only scratched the surface but there exist here some techniques that are practical to use in many scenarios Thanks for reading All
