海外TECH	DEV Community	JavaScript Tips, Tricks and Best Practices	https://dev.to/kpiteng/javascript-tips-tricks-and-best-practices-33dm	JavaScript Tips Tricks and Best PracticesHello Developers In this tech article I will cover JavaScript Trips Tricks and Best Practices In daily coding many times we wrote a long lines of code read this article I am going to cover best javascript practices tips amp tricks to reduce lines of code and minimize your works using JavaScript in built functions I will cover array of JavaScript function along with example right away So Let s Start Take away Replace AllGroup By Array Of ObjectsNext next Map map Cast Values in array using map Filter filter Find Index findIndex Best Practice Avoid If Else SwitchDestructuring Assignment Smart Tips Numeric SeparatorsGet Unique Elements Remove Duplicate Objects From Array Promise AnyLogical Assignment Operators Replace All replaceAll arg arg replaceAll arg arg Easily replace all the characters that you specify in a string without using a regex It takes two arguments arg the character you want to replace and arg the character you want to replace it by const string Javascript is the best web scripting language Javascript can be used for both front end and backend console log string replace Javascript Typescript output Typescript is the best web scripting language Typescript can be used for both front end and backendlet myStr Prograssing console log myStr replaceAll “s “m output Programming Group By Array Of Objects reduce Very Important Tricks Many times we need to group result from array Let s check how reduce help us to achieve over here I have sent two arguments arg arrCity array arg region key name on which you want to apply group var arrCity region Europe name Paris region Europe name Amsterdam region Europe name Vienna region UnitedStates name New York region UnitedStates name San Francisco region Europe name Barcelona var groupBy function xs key return xs reduce function rv x rv x key rv x key push x return rv var resultByRegion groupBy arrCity region pass array amp key nameconsole log resultByRegion output Europe name Paris region Europe name Amsterdam region Europe name Vienna region Europe name Barcelona region Europe UnitedStates name New York region UnitedStates name San Francisco region UnitedStates Next next Many times we are required to take a unique number for our business logic and we try random functions but it might chance it will repeat the same number again Try next will give you a unique number every time function getUniqueID var uniqueNumber while true yield uniqueNumber const uniqueID getUniqueID console log uniqueID next value output console log uniqueID next value output console log uniqueID next value output Map map Map is widely used by developers in daily coding Map offers various use cases depending upon your custom requirement Let s check in code var arrCity id name London region UK id name Paris region Europe id name New York region United State const arrCityName arrCity map city gt city name console log arrCityName output London Paris New York Many times we required to add new key pari within existing array Let s do that Let s use arrCity over here arrCity map city gt city cityWithName city name city region console log arrCity output cityWithName London UK new key pair id name London region UK cityWithName Paris Europe new key pair id name Paris region Europe cityWithName New York United State new key pair id name New York region United State Let s use another approach and add new key pair value We will use same array arrCity over here const newArrCity arrCity map city gt city newCity true console log newArrCity output id name London newCity true new key pair region UK id name Paris newCity true new key pair region Europe id name New York newCity true new key pair region United State Cast Values in array using map Awesome tricks harness the power of map function you will convert an array of strings into an array of numbers const arrStringValues const arrNumbers arrStringValues map Number console log arrNumbers output Filter filter Consider you have an array and you want to take only relevant data use filter and apply your criteria it will return you filter result var arrCity region Europe name Paris region Europe name Amsterdam region Europe name Vienna region UnitedStates name New York region UnitedStates name San Francisco region Europe name Barcelona const arrEuropeCity arrCity filter city gt city region Europe console log arrEuropeCity output name Paris region Europe name Amsterdam region Europe name Vienna region Europe name Barcelona region Europe Find Index findIndex Very useful on daily coding It s simple trick to find index of object from arrayconst arrCity id name London id name Paris id name New York const index arrCity findIndex city gt city name Paris console log index output Best Practice Avoid If Else SwitchMany times we write conditional code either we use if else Or switch I would suggest best code practice here and use smart trick Let s check how it is going with If Else function getCityInformation city if city toLowerCase london return Welcome to London else if rhyme toLowerCase paris return Welcome to Paris else if rhyme toLowerCase amsterdam return Welcome to Amsterdam return We re Sorry No City Found const londonCityInfo getCityInformation London console log londonCityInfo output Welcome to London Let s avoid If Else OR Switch and use our TRICK here function getCityInformation city const cityInfo london Welcome to London paris Welcome to Paris amsterdam Welcome to Amsterdam return cityInfo city toLowerCase We re Sorry No City Found const pariseCityInfo getCityInformation Paris console log pariseCityInfo output Welcome to Paris Destructuring Assignment Smart Tips All you know about props extractor very well its bit similar kind of syntax where you can give ALIAS NAME which you extract from object which return you the smart result Let s Check const region id name Europe city Paris Vienna Amsterdam const id name region const paris amsterdam region city console log id console log name Europeconsole log paris Parisconsole log amsterdam Amsterdam Numeric SeparatorsNumeric separators are one of the useful features that have been introduced in ES This makes it easier to read large numbers in JavaScript by providing separation between digits using underscores let myNumber console log myNumber output let num console log num output e Get Unique Elements Remove Duplicate Objects From ArrayWhat do you do to get unique elements from an array manual iterate and check if an element exists or not Let s try Set function to get unique results const arrIndex const arrCity Paris London New York Paris Chicago const uniqueIndex new Set arrIndex const uniqueCity new Set arrCity console log uniqueIndex output console log uniqueCity output Paris London New York Chicago Promise AnyPromise any takes an array of promises as an argument If all the promises are resolved then only it will return a result It will wait until all promises complete their tasks no matter whether it s resolve reject const promise new Promise resolve reject gt resolve promise was resolved const promise new Promise resolve reject gt resolve promise was resolved const promise new Promise resolve reject gt resolve promise was resolved let result Promise any promise promise promise console log result output promise was resolved promise was resolved promise was resolved Logical Assignment OperatorsES come out with three useful logical assignment operators amp amp and The logical assignment operator amp amp is used between two values If the first value is truthy the second value will be assigned to it let firstNumber let secondNumber firstNumber amp amp secondNumber output console log firstNumber output Here is an equivalent to it if firstNumber firstNumber secondNumber The logical assignment operator is also used between two values If the first value is not truthy falsy the second value will be assigned to it let firstNumber null let secondNumber firstNumber secondNumber output console log firstNumber output Here is an equivalent to it if firstNumber firstNumber secondNumber The logical assignment operator checks if the first value is null or undefined If it is the second value is assigned to it when first value is null or undefinedlet firstNumber null let secondNumber firstNumber secondNumber output console log firstNumber output when first value is truthyfirstNumber firstNumber secondNumber output console log firstNumber output Here is an equivalent to it if firstNumber null firstNumber undefined firstNumber secondNumber Thanks for reading Article KPITENG DIGITAL
