海外TECH	DEV Community	Currying Existing Functions with JavaScript	https://dev.to/anewman15/currying-existing-functions-with-javascript-4nnc	Currying Existing Functions with JavaScriptThis post is about transforming an already defined polyadic function into a curried function This is the third post in a series on curried functions titled Curry Functions in JavaScript This follows the previous post named Basic Curried Functions in JavaScript Basic vs Advanced CurryingBasic curried functions are different from more advanced ones because basic currying doesn t involve taking a function as an argument whereas more advanced ones do Basic curried functions are defined from scratch whereas advanced currying involves using an already existing multary function From a higher level currying is more of an approach of transforming an otherwise uncurried function to return a series of unary functions regardless of whether it is hardcoded by the author or transformed at runtime We will consider several advanced cases differing in their complexity levels first one involving a wrapper function defined manually from ground up but basing it on the passed to be curried function In the upcoming posts we will also cover auto currying variadic currying infinite currying and currying to a fixed arity This article covers currying existing functions manually Currying Existing Functions ManuallyIn this example we ll use the createMessage function we wrote in the previous post named Basic Curried Functions in JavaScript Let s say we have the function that returns the message string in hand function createMessage greeting name message return greeting name message Instead of writing a curried function from scratch for the above function like this function createMessage greeting return function name return function message return greeting name message we can use the existing multary function by passing it to a wrapper function and then build the wrapper function on top of it function curryATernaryFunction f return function greeting return function name return function message return f greeting name message Then calling the wrapper function with createMessage will give us the curried function We can use it for our purposes afterwards const curriedCreateMessage curryATernaryFunction createMessage console log curriedCreateMessage Hi Haskell Whadup Hi Haskell Whadup I named the above function curryATernaryFunction because I wanted to play with it a bit We can actually curry other ternary functions those that take three arguments with it function addThreeThings one two three return one two three console log curryATernaryFunction addThreeThings Hi Haskell Whadup HiHaskellWhadup console log curryATernaryFunction addThreeThings How it works The wrapper function is called an accumulator Its purpose is to store all the passed in arguments and make them available to the multary function It uses nested closures the returned functions at each level of nesting along with their lexical environments to accumulate all the arguments for the final returned function The way it works is every time a returned function is invoked and it takes its given argument the argument is held at its immediately nested function s lexical scope which makes it available to deeper ones via their scope chain So our core function s execution context is able to access all the arguments	2022-07-31 05:20:00
海外TECH	DEV Community	7 Tips to Transition from a Beginner to an Intermediate Frontend Developer 🤓 👨‍💻	https://dev.to/ruppysuppy/7-tips-to-transition-from-a-beginner-to-an-intermediate-frontend-developer-lec	Tips to Transition from a Beginner to an Intermediate Frontend Developer ‍So you have learned the basics of HTML CSS and JS created a few sites and perhaps even landed a junior role too Now what There is a plethora of information on how to get started but the path becomes a bit blurry once you nail the basics This article will help you transition from a beginner to an intermediate developer so buckle up your seat belt and get ready to learn Go VanillaNo we are not talking about ice creams This will turn out to be excruciatingly difficult at first but ditching third party code forces you to learn how every piece of your application works You will need to focus on creating reusable utilities for things such as selecting elements manipulating the DOM and handling requests The development will be slow but the goal isn t to build things quickly but rather to understand the building blocks of your craft Keep a Single Source of Truth stay DRY Again we are not talking about drying ourselves but keeping the code DRY Don t Repeat Yourself Why is it important The importance of writing code that adheres to the DRY principle is that you have to refer to only one place when looking up a certain definition inside your code repository To modify the functionality you only have to change your code in a single place and you are done Learn Regular ExpressionsRegular Expressions also known as RegEx is an incredibly powerful tool in your arsenal It is used to find matching patterns in text It has a host of applications ranging from email validationconst emailValidatorRegex s s s const isValid email gt emailValidatorRegex test email isValid dummyemail gmail com validisValid dummyemail email co validisValid dummyemail gmail co in validisValid dummyemail gmail invalidText formattingconst normalFunction function add x y return x y const formattedFunctionRegex

crucial to accept that even if you believe in a certain way of doing something there might be something that comes along to solve your problem more effectively It s good to listen to the opinions of others but many developers fall into the trap of believing that their way is the best Every method has its pros and cons Every project has its own needs and it is essential to take those into account instead of simply following the method you know Be Business AwareAt the end of the day most people have bills to pay Unless you are a hobbyist you will probably have clients deadlines and budgets looming over your head Becoming a mid level developer is as much about what you know as it is about the responsibility you can take on and your commitment to delivering the best you reasonably can in the time you re given If you create the best website the world has ever seen but it is a month late it won t reflect on you well Senior developers are paid what they re paid because they re reliable Yes they can solve problems faster and know a lot but they will also do what it takes to deliver a project on time They understand which technologies and approaches will fit the needs of a project without being overkill Be Patient and Keep PracticingThe tech landscape is ever changing but don t go chasing after every shiny new framework You can t go wrong with simply improving your fundamental skills Let s say you want to eventually be a React developer Yes learning React now would certainly get you into the ecosystem faster but ignoring what React is built on plain old JavaScript can limit you in the future Programming is a long game it takes years to become a truly competent developer and the more you know the more you realize you don t know very much at all Be persistent but patient and you will become a great developer right under your own nose Build a strong foundation your future self will thank you Don t Forget to Have Fun Don t get so caught up in making a living that you forget to live life It is crucial to spare some time to build your dream project regardless of the work pressure Often people get so engrossed in their day to day life that they forget what lit the fire in their hearts to start development in the first place It is also essential to take a break from time to time if you keep coding x you will definitely grow to detest it amp quite naturally your productivity will plummet That s all folks Research says writing down your goals on pen amp paper makes you to more likely to achieve them Check out these notebooks and journals to make the journey of
