Core JavaScript: Scope |
https://dev.to/ioanat94/core-javascript-scope-29cm
|
Core JavaScript Scope 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 a 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 You might recall that in a previous article we came across the concept of scope in JavaScript In short scope represents the section of code in which a variable is accessible There are a few different types of scope in JavaScript Global scopeModule scopeFunction scopeBlock scopeLet s go through each of them to see how they work Global scopeThe global scope exists outside of any functions Variables declared in the global scope are called global variables and they can be accessed anywhere in the code const name Jane Global variable in global scopefunction greet console log Hello name Hello Jane Note If you assign a value to a variable that has not yet been declared it automatically becomes a global variable unless you are using strict mode function greet name Jane console log Hello name Hello Jane Module scopeWith the introduction of modules in ES also came the concept of module scope Consider the following module greeting greeting jsconst name John console log Hello name Let s import the module into a different file and try to access name import greeting js console log name This will throw an error because name is not accessible outside its module greeting unless it is exported Function scopeIn JavaScript each function creates its own scope Variables declared within a function scope are called local variables and they can only be accessed within the function they have been declared in function greet const name John Local variable in function scope console log Hello name greet Hello John console log name ReferenceError name is not defined Block scopeBlock scope is the scope that exists within a pair of curly brackets Variables declared within a block scope are only accessible within that scope if true const name John Block scoped variable console log Hello name Hello John console log name ReferenceError name is not definedNote var variables behave differently in this scenario they are not block scoped var variables can be accessed outside of the block scope but not outside of the function scope if true var name John Block scoped variable console log Hello name Hello John console log name John Scope nestingIn JavaScript scopes can be nested meaning that a scope can exist inside another scope function greet Function scope of the greet function const name John if name John Block scope of the if statement const greeting Hello console log greeting name Hello John console log greeting ReferenceError greeting is not defined The scope of the greet function is called the outer scope and the scope of the if statement is called the inner scope The important takeaway here is that variables declared in the outer scope can be accessed in the inner scope but variables declared in the inner scope cannot be accessed in the outer scope Scope chainWhenever you try to access a variable within your code the search process begins from the local scope of the function you are calling If the variable does not exist in the local scope the search moves on to the outer scope e g the scope of a parent function until it reaches the outermost scope of the code the global scope This path that the code goes down in order to find the variable is known as the scope chain If the variable is not found anywhere along the way you will get a ReferenceError PracticeWhat are the outputs of these code snippets function greet let name John console log Hello name name Jane greet console log Hello name Answer Hello John Hello Jane Reason The name inside of the greet function is a local variable so it cannot be changed from outside of the function name Jane essentially creates a new global variable let name John if true let name Jane console log name Answer JohnReason The name variable with the value Jane is created within the block scope of the if statement Therefore it cannot be accessed from the global scope Instead name will have the value given to it in the global scope which is John let name John if true var name Jane console log name Answer SyntaxError Identifier name has already been declaredReason var does not follow the same rules as let and const its declaration will be global despite being placed inside of the if block Therefore the code will throw an error as name has already been declared in the global scope Thank you for reading this 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 |
