海外TECH	DEV Community	Javascript Clean Code Tips & Good Practices	https://dev.to/apoorvtyagi/javascript-clean-code-tips-good-practices-2od4	Javascript Clean Code Tips amp Good PracticesCode should be written in such a way that is self explanatory easy to understand and easy to modify or extend for the new features Because code is read more than it is written that s why so much emphasis is given to clean code The more readable our source code is The easier it is to maintain The less time required to understand an implementation for a new developer The easier it is to discover what code can be reusedIn this blog post I will share some general clean coding principles that I ve adopted over time as well as some JavaScript specific clean code practices NamingDon t turn naming into a riddle game Name your variables and functions in a way that they reveal the intention behind why they were created in the first place This way they become searchable and easier to understand if let s say a new developer joins the team Only go for Shortening and abbreviating names when you want the next developer working on your code to guess what you were thinking about Bad let x let y new Date getFullYear if x gt if y x gt Good let userAge let currentYear new Date getFullYear if userAge gt if currentYear userAge gt Also don t add extra unnecessary letters to the variable or functions names Bad let nameValue function theProduct Good let name function product ConditionalsAvoid negative conditionals Negatives are just a bit harder to understand than positives Bad if isUserExist user Good if isUserExist user Functions should do one thingThe function should not have more than an average of lines excluding spaces and comments The smaller the function the better it is to understand and refactor Try making sure your function is either modifying or querying something but not both Use default argumentsUse default arguments instead of short circuiting or conditionals Default arguments are often cleaner than short circuiting Remember that if you use them your function will only provide default values for undefined arguments Other falsy values such as false null and NaN will not be replaced by a default value Bad function getUserData name const userName userName Patrick Collision Good function getUserData name Patrick Collision Single Level of Abstraction SLA While writing any function if you have more than one level of abstraction your function is usually doing more than one thing Dividing a bigger function into multiple functions leads to reusability and easier testing Functions should do one thing They should do it well They should do it only ーRobert C MartinBad function checkSomething statement const REGEXES const statements statement split const tokens REGEXES forEach REGEX gt statements forEach statement gt const names tokens forEach token gt lex names forEach node gt parse Good function checkSomething statement const tokens tokenize statement const syntaxTree parse tokens syntaxTree forEach node gt parse function tokenize code const REGEXES const statements code split const tokens REGEXES forEach REGEX gt statements forEach statement gt tokens push return tokens function parse tokens const syntaxTree tokens forEach token gt syntaxTree push return syntaxTree Don t ignore caught errorsDoing nothing with a caught error doesn t give you the ability to fix or react to that particular error Logging the error to the console console log isn t much better as oftentimes it can get lost among other things printed to the console If you wrap any bit of code in a try catch it means you think an error may occur there and therefore you should have a plan for when it occurs Bad try functionThatMightThrow catch error console log error Good try functionThatMightThrow catch error notifyUserOfError error reportErrorToService error Minimize CommentsOnly comment the part of the code that has business logic complexity Comments are not a requirement Good code mostly documents itself Bad function hashing data The hash let hash Length of string const length data length Loop through every character in data for let i i lt length i Get character code const char data charCodeAt i Make the hash hash hash lt lt hash char Convert to bit integer hash amp hash Good function hashing data let hash const length data length for let i i lt length i const char data charCodeAt i hash hash lt lt hash char Convert to bit integer hash amp hash “Redundant comments are just places to collect lies and misinformation ーRobert C Martin Remove commented codeDon t leave commented out code in your codebase Version control exists for a reason Leave old code in your history If you ever need them back pick them up from your git history Bad doSomething doOtherStuff doSomeMoreStuff doSoMuchStuff Good doSomething Import only what you needDestructuring was introduced with ES It makes it possible to unpack values from arrays or properties from objects into distinct variables You can use this for any kind of object or module For instance if you only require to add and subtract function from another module Bad const calculate require calculations calculate add calculate subtract Good const add subtract require calculations add calculate subtract It makes sense to only import the functions you need to use in your file instead of the whole module and then access the specific functions from it Keep Function arguments or less ideally Limiting the number of function parameters is really important because it makes testing your function easier Having more than three parameters leads you to test tons of different cases with each separate argument arguments are the ideal case anything above that should be avoided if possible Usually if you have more than three arguments then your function is trying to do too much Which ultimately leads to the violation of the SRP Single Responsibility Principle Use array spreads to copy arrays Bad const len items length const itemsCopy let i for i i lt len i itemsCopy i items i Good const itemsCopy items Write linear codeNested code is hard to understand Always write the linear code as much as possible It makes our code simple clean easy to read and maintain thus making developer life easier For Example Using promises over callbacks can increase readability multiple times Use ESLint and PrettierAlways use ESLint and Prettier to enforce common coding styles across teams and developers Also try and use JavaScript s latest features to write code like destructuring spread operator async await template literals optional chaining and more Use proper parenthesesWhen working with operators enclose them in parentheses The only exception is the standard arithmetic operators and since their precedence is broadly understood It is highly recommended to enclose and in parentheses because their precedence can be ambiguous when they are used together This improves readability and clarifies the developer s intention Bad const foo a amp amp b lt c gt d if a b amp amp c return d Good const foo a amp amp b lt c gt d if a b amp amp c return d Make sure your code doesn t lead to situations like this Return early from functionsTo avoid deep nesting of if statements always return a function s value as early as possible Bad function isPercentage val if val gt if val lt return true else return false else return false Good function isPercentage val if val lt return false if val gt return false return true This particular example can even improve further function isPercentage val var isInRange val gt amp amp val lt return isInRange Similarly the same thing can be applied to Loops as well Looping over large cycles can surely consume a lot of time That is why you should always try to break out of a loop as early as possible ConclusionThere s a saying in the development community that you should always write your code like the next developer that comes after you is a serial killer Following this rule I have shared tips here that can probably save you from your fellow developers when they will look into your code If you find any updates or corrections to improve these tips or want to add one of your own that you think can be helpful please feel free to share them in the comments For further reading I would highly suggest you go through these resources Airbnb
