海外TECH DEV Community Front End Interview Question https://dev.to/lucvankerkvoort/front-end-interview-question-5392 Front End Interview QuestionWe as programmers lead a hard life Especially when it comes to the interview process There are many obstacles we have to face to get a new job which is never fun to do I bet all of you reading this are excellent programmers but a lot of us have a problem when we get put on the spot performing under pressure is not our forte This is why we didn t become olympic swimmers or deep sea divers All jokes aside I think it is important for us to document the hoops we have to jump through to get a job That is why I wrote this article about a take home assignment I once received from a company The AssignmentI received the following requirementsCreate a button that once clicked showcases the current price of BitcoinAfter the button is clicked the buttons text changes from get Bitcoin price to refresh Bitcoin price After the button is clicked it changes color from blue to purpleOnce the button is clicked a field shows up with Current price after a consecutive click a second field shows up with Previous price This was the entirety of the brief the assignment had little to no restrictions to it You can use libraries however you like them You can use outside sources to fill in the code and you have hour to complete it The ApproachI started thinking about how I wanted to structure the code keeping in mind best practices and going for a functional programming solution In functional programming we break big problems down into modular solutions This means we build functions that are reusable and pure LogicSo I started dividing up the work and I came up with the following approach and pseudo code for the logic Button pressI ll use a useState to keep track of the button state This is also a value we can pass along to the button to change the color of it and use it to set the text for it Button pressconst isPressed setPressed useState false API callI ll create a modular API call for the bitcoin call with a try catch statement which will return an empty array so the page will still load even if the call fails API callconst getBitcoin async gt try fetch url catch return Setting Amountthinking about this we need a data structure to keep track of the bitcoin prices In my mind the best approach would be a Queue where a price comes in and we display it as current then a second price comes in and current becomes the new price and the old price becomes the previous price and so on and so forth setting amountconst bitcoinPrices setPrice useState const setAmount data gt const newPrices data bitcoinPrices slice setPrice newPrices These will guide me into creating the application User InterfaceNow We ll have to build out the UI for this application Let me add that the UI looks kind of funky because there were no restrictions to what the UI looks like this was purely a showcase of logic skills lt div className App gt lt button gt isPressed refresh Bitcoin price get Bitcoin price lt button gt lt div gt lt div gt bitcoinPrice map value i gt lt div key i gt i Current price Previous price value lt div gt lt div gt lt div gt lt div gt as you can see I put in a ternary changing the text of the button from get Bitcoin price to refresh Bitcoin price I am mapping the bitcoinPrice state variable to set the value I m using a ternary to decide the text in front of the value If it is the index of we set it to Current Price otherwise we set it to Previous Price Extra curricular pointsIn this challenge I had to build it on my own machine while the interviewer was watching I created a new React project using npx create react app I got prompted the question why I used create react app These kind of questions are a great tool to share your knowledge It is extra curricular points to know the answers to these kind of questions so if you don t that is okay but here is an acceptable answer to the questioncreate react app is a package that presets an entire React application which installs babel which is a compiler used to parse JSX code to plain ES JavaScript it installs webpack a bundler and presets it to bundle the application installs React and presets the Virtual DOM sets up testing with React testing library so right out of the box we can start coding away The other good thing about it is that you can install and talk at the same time Hopefully by the time you are done talking the installation will be complete The ExecutionUnder the watchful eye from my interviewer I started building out the application first a draft version to get things started function App const isPressed setPressed useState false const bitcoinPrice setBitcoinPrice useState const getBitcoin async gt try const call await fetch method GET authorization Bearer abddffabcdabfdbbccdebcdcecc const response await call json return await response catch return const setAmount gt const data await getBitcoin if data returnconsole log data data base BTC currency USD amount const data amount data New amount is pushed in front of the old amounts that have been deconstructed We then slice the array at so we get rid of any old data we don t want to use anymoreconst newPrices amount bitcoinPrice slice setBitcoinPrice newPrices return lt div className App gt lt button onClick gt if isPressed setPressed true setAmount gt isPressed refresh Bitcoin price get Bitcoin price lt button gt lt div gt lt div gt bitcoinPrice map value i gt lt div key i gt i Current price Previous price value lt div gt lt div gt lt div gt lt div gt export default AppHere I build the draft for the application I felt like it is a lot of code on a single page but it was executing everything I needed for the logic however on the User Interfaces the button wasn t changing color yet so we had to tackle that with a library I asked the interviewer if I m allowed to install libraries He said yes but you would have to explain the use case of the library I decided I wanted to implement styled components as a CSS library that allows me to send and use JavaScript right into my CSS This is extremely handy if you have to set colors on elements using a ternary operator StylesI created the following css file to style the Button and implemented the ternary operator to change the background color to purple after the button has been pressed I also found that the list items were horizontally aligning to each other so I decided to use flexbox to fix that issue as you can see in the List componentimport styled from styled components export const Button styled button background color isPressed gt isPressed blue purple export const List styled div display flex flex direction column with that out of the way I imported the components into the main file and I implemented the new styled components as shown below return lt div className App gt lt Button isPressed isPressed onClick gt if isPressed setPressed true setAmount gt isPressed refresh Bitcoin price get Bitcoin price lt Button gt lt div gt lt List gt bitcoinPrice map value i gt lt div key i gt i Current price Previous price value lt div gt lt List gt lt div gt lt div gt Now I was happy about the styling and I could move forward with optimization of my code OptimizationDuring the interview I started thinking whether my code was written with the best practices when it comes to writing functional programming I did see a flaw in my setAmount functionconst setAmount gt const data await getBitcoin if data returnconsole log data data base BTC currency USD amount const data amount data New amount is pushed in front of the old amounts that have been deconstructed We then slice the array at so we get rid of any old data we don t want to use anymoreconst newPrices amount bitcoinPrice slice setBitcoinPrice newPrices this function is not a pure function Meaning with the same input we do not always receive the same output It should also not be modifying any outside variables or have functions as children I felt like this could be optimized by using composition Composition or Pipingcomposing functions means we have a higher order function that executes a multitude of functions on a singular input Meaning we give parameters to a function that then executes multiple functions in sequence utilizing the parameters reading from right to left e g const purchaseItem compose subtractFunds emptyBasket moveToPurchase putInBasket name Laptop price Piping is the same concept but then the other way around Instead of right to left we go left to rightconst purchaseItem pipe putInBasket moveToPurchase emptyBasket subtractFunds name Laptop price I found a great solution to compose asynchronously What this means is that I have created a compose function which takes in promises and converts those into actual dataexport const compose functions gt input gt functions reduceRight chain func gt chain then func Promise resolve input These powerful few lines create a composition HOF higher order function that resolves promisesFirst functionwe give it x amount of functions in the first function of the chain which we use a spread operator on so we can have any amount of functions Second functionwe take input in a second function so we can curry the input on to the functions as seen in the example above Third functionthis is what the actual function returns it is a reducer that takes in chain and function the chain is used to create a resolve for the functions and resolves the given input through these chains I know right take a breather after this one The SolutionThe solution comes down to a couple of core concepts being applied to a core problem as stated we had the following requirements Create a button that once clicked showcases the current price of BitcoinAfter the button is clicked the buttons text changes from get Bitcoin price to refresh Bitcoin price After the button is clicked it changes color from blue to purpleOnce the button is clicked a field shows up with Current price after a consecutive click a second field shows up with Previous price The following paradigms are used to solve the issue modularizationfunctional programmingcomposinghere is a snapshot of the architecture implemented for this solutionThe following files are highlighted App js this stores the applicationstyles js this is holds our styled components utils folder with utility functions in this case the compose function API folder with API calls in this case the bitcoin apiThe reason I chose this file structure is that it gives room for growth utility functions are really used a lot storing these in an easy to reach folder is beneficial to a team working on an application Setting up webpack to import from the src folder is even better because these folders will be accessible anywhere instead of having the write relative paths let s take a close look at App jsimport React useState from react import getBitcoin from API import compose from utils import Button List from styles import App css function App const hasBeenPressed setPressed useState false const bitcoinPrice setBitcoinPrice useState const storeAmount data gt if data return const amount data const bitcoinPrices amount bitcoinPrice slice setBitcoinPrice bitcoinPrices const bitcoinCall compose storeAmount getBitcoin return lt div className App gt lt Button isPressed hasBeenPressed onClick gt if hasBeenPressed setPressed true bitcoinCall gt hasBeenPressed refresh Bitcoin price get Bitcoin price lt Button gt lt div gt lt List gt bitcoinPrice map value i gt lt div key i gt i Current price Previous price value lt div gt lt List gt lt div gt lt div gt export default App as you can see I modularized some of the code for example we are now importing the compose function as well as the API call for bitcoin since the bitcoin API call returns a promise we use our special compose function to resolve that promise and pass on the data to the setAmount function const bitcoinPrice setBitcoinPrice useState const storeAmount data gt if data return const amount data const bitcoinPrices amount bitcoinPrice slice setBitcoinPrice bitcoinPrices const bitcoinCall compose storeAmount getBitcoin As you can see I utilized the styled components to create the button and the list components Button component lt Button isPressed hasBeenPressed onClick gt if hasBeenPressed setPressed true bitcoinCall gt hasBeenPressed refresh Bitcoin price get Bitcoin price lt Button gt as you can see I m passing on the hasBeenPressed to Button component which is used in the styled component to change the background I m also using it to set the text utilizing a ternary operator List component lt List gt bitcoinPrice map value i gt lt div key i gt i Current price Previous price value lt div gt lt List gt List is used for styling purposes only making sure the div s are centered and in a column direction HelpersI always like to create folders for my helper functions so it is structured and easily maintainable These are the folders I created and I usually use the index js format because these are easily accessible utilsexport const compose functions gt input gt functions reduceRight chain func gt chain then func Promise resolve input APIexport const getBitcoin async gt try const call await fetch method GET authorization Bearer abddffabcdabfdbbccdebcdcecc const response await call json return await response catch return named exports are easy to import again as well it also separates the different functions instead of exporting default and having a load of different files Thank youThank you so much for reading this tutorial I hope it has given you an insight into how to approach a problem like this I know this is an opinionated way of writing code but I believe that if you have a foundation that you are following and a good explanation to why you do the things you do you are an excellent programmer if you want
