海外TECH	DEV Community	Javascript Objects: Best Practices	https://dev.to/codecraftjs/javascript-objects-best-practices-gjo	Javascript Objects Best PracticesWhile working on Javascript we have to deal with objects as its a building block of the Javascript Knowing how to use the objects effectively makes your code more readable efficient and bug free In this blog we are going to see a few good practices while working with objects in Javascript So lets get started Tip Use the literal syntax for object creationThis seems to be a small change while initialising the objects variable but after knowing this information you will better understand why this is important not recommendedconst item new Object good practiceconst item Simplicity and Readability The literal syntax provides a concise and intuitive way to define objects It is easier to read and understand compared to the Object constructor which requires invoking a function with the new keyword Consistency Using the literal syntax ensures consistency in code style throughout your project Most developers are accustomed to seeing objects defined using the literal syntax making the code more familiar and easier to maintain Performance Creating objects with the literal syntax is faster compared to using the Object constructor The literal syntax directly creates the object without invoking any additional functions or constructors Prototype Chain Preservation When using the Object constructor the newly created object doesn t inherit from the global Object prototype In contrast when using the literal syntax the object is created with the correct prototype chain intact Immutability When using the literal syntax it s easier to create immutable objects by using techniques such as Object freeze or ES s object spread syntax which can make the object properties read only This immutability helps prevent unintended modifications to the object Syntax Errors Avoidance The literal syntax allows for more flexibility when defining objects such as using computed property names key value shorthand property syntax key or object methods method These features are not available when using the Object constructor While there may be some rare cases where using the Object constructor is necessary e g when creating objects with specific prototypes in general the literal syntax offers a simpler more readable and performant way to create objects in JavaScript Tip Use computed property namesfunction getKey k return k key generates key name dynamically not recommendedconst obj id name Foo obj getKey enabled true good practice const obj id name Foo getKey enabled true computed property syntax This will allow to define all the properties at once while creating the object Tip Use object method and property shorthanduse object method shorthand looks uglyconst obj value addValue function value return this value value looks clean const obj value addValue value return this value value use property value shorthandconst property property looks uglyconst obj property property good practiceconst obj property Group all shorthand properties at the beginning of your object declaration In this way it s easier to see which properties are using the shorthand Tip Provide quotes for properties with invalid identifiersThere is no need to quote all the properties defined inside the object This hampers the readability and object looks bulky If you are using any invalid identifiers such as identifiers with kebab cases then you can quote that particular property bulkyconst obj prop prop prop good practice const obj prop prop prop Tip shallow deep copy object to avoid object mutabilityThere are few tricks and methods which allows the object to be copied to another object variable to avoid mutating the original object Based on the requirement we can create a shallow copy or deep copy of the original object or else completely store the reference of the original object into another object variable avoid using Object assign in this wayconst originalObj a b const copiedObj Object assign originalObj c this mutates originalObj delete copiedObj a this will be deleted from the originalObj as well shallow copy using Object assignconst originalObj a b const copiedObj Object assign originalObj c copy gt a b c delete copiedObj aconsole log originalObj a b console log copiedObj b c a is deleted from copiedObjshallow copy using spread object syntaxconst originalObj a b const copiedObj originalObj c copy gt a b c delete copiedObj aconsole log originalObj a b console log copiedObj b c a is deleted from copiedObjdeep copy using JSON parse and JSON stringifyconst originalObj a b b b const copiedObj JSON parse JSON stringify originalObj copy gt a b b b delete copiedObj b bconsole log originalObj a b b b console log copiedObj a b b	2023-06-17 08:24:11
