海外TECH DEV Community Core JavaScript: Var vs. Let vs. Const https://dev.to/ioanat94/core-javascript-var-vs-let-vs-const-39d7 Core JavaScript Var vs Let vs Const About the seriesCore JavaScript is a series I m writing that covers as the name suggests some of the core principles of JavaScript It originally started as study or reference material for myself but I decided to share it with the community in the hopes that it will prove useful for others This series is intended for beginner JavaScript developers or more experienced developers in need of a refresher I have a few topics planned out already but I would love to hear from you if there are any topics in particular you would be interested to read about In this article I will go over the different ways of declaring variables in JavaScript their characteristics redeclarability reassignability scope and hoisting and when to use which At the end there will be a few exercises to practice the concepts I talked about Below is a quick summary of the main characteristics of each variable declaration RedeclarableReassignableScopeHoistingvarglobal functionhoisted initializedletblockhoisted not initializedconstblockhoisted not initialized VarBefore ES var was the only option for declaring variables in JavaScript but it came with a few problems For example var variables can be redeclared which means that doing something like this is perfectly valid var name Steve var name Chris This is not an issue if you re doing it intentionally The problem arises when you may not be aware that a certain variable has been declared already This can lead to unexpected outputs errors bugs and headaches Another characteristic of var variables is that they can be reassigned which means you can freely change their value after they ve been declared var age age In terms of scope var variables are either in the global scope if they have been declared outside of a function or in the function scope if they have been declared inside of a function We will talk more about scope in a future article but if you would like to learn more about it now check out this article on MDN var yellowFruit banana outside of function gt global scopefunction f var redFruit strawberry inside of function gt function scope console log redFruit ReferenceError redFruit is not defined because redFruit is not in the global scopeIn terms of hoisting var variables are hoisted to the top of their scope and initialized with the value of undefined We will talk more about hoisting in a future article but if you would like to learn more about it now check out this article on MDN What we writeconsole log favoriteSeason var favoriteSeason spring How it s interpretedvar favoriteSeason console log favoriteSeason favoriteSeason spring Letlet solves one of the major issues that come with var let variables are not redeclarable in the same scope more on this later You don t have to worry about accidentally creating bugs in your code by redeclaring a variable that has already been declared Doing this for example is not allowed let name Steve let name Chris SyntaxError Identifier name has already been declaredJust like var let variables can also be reassigned let age age In terms of scope let variables are block scoped A block is any code written between a pair of curly brackets Remember how let variables are not redeclarable in the same scope They are however redeclarable if they are in different scopes as illustrated below let yellowFruit banana if true let yellowFruit lemon console log yellowFruit lemon console log yellowFruit bananaIn terms of hoisting let variables are hoisted to the top of their scope but they are not initialized This means that you cannot use let variables before declaring them console log favoriteSeason let favoriteSeason spring ReferenceError favoriteSeason is not defined ConstJust like let const variables can also not be redeclared const name Steve const name Chris SyntaxError Identifier name has already been declaredUnlike both var and let const variables can not be reassigned const age age TypeError Assignment to constant variable When it comes to Objects declared with const the Object itself cannot be reassigned but the individual properties within the Object can be const student name Alice age student name Kelly works finestudent name Susan TypeError Assignment to constant variable age Just like let const variables are block scoped const yellowFruit banana if true const yellowFruit lemon console log yellowFruit lemon console log yellowFruit bananaJust like let const variables are hoisted to the top of their scope but they are not initialized console log favoriteSeason const favoriteSeason spring ReferenceError favoriteSeason is not defined When to Use Which For let and const there are two main approaches regarding when to use which Use let by default switch to const when you need a variable to remain constant Use const by default switch to let when you need a variable to be reassignable What about var The general consensus among JavaScript developers is that in modern JavaScript YOU SHOULD NEVER USE VAR under any circumstances var is simply worse compared to let and const and there is no good reason to ever use it Also there s a chance your tech lead will hunt you down if they see var in your pull requests PracticeWhat are the outputs of these code snippets if true var year let model Golf console log year console log model Answer ReferenceError model is not definedReason model is declared using let which means its scope is restricted to the code block of the if statement Trying to access it outside of its scope will cause an error year is declared using var which is not block scoped and therefore can be accessed outside of the if statement for var i i lt i console log Looping console log i Answer Looping Looping Looping Reason In this case var is declared globally therefore i is accessible outside of the for loop for let i i lt i console log Looping console log i Answer Looping Looping Looping Uncaught ReferenceError i is not definedReason Because let is block scoped i is restricted to the for loop and cannot be accessed outside of it Thank you for reading the second article in my Core JavaScript series If you found this useful if you have anything to add or if I made any mistakes I would love to hear from you I m also very open to suggestions for future topics for the series Expect to see the next part soon Thanks and see you there 2022-09-07 11:24:29
