Editor to share with you the JavaScript function scope of the example analysis, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

Function scope

Variables declared locally (within a function) have function scope.

Example

/ / the code here cannot use carNamefunction myFunction () {var carName = "porsche"; / / code here CAN use carName} / / the code here cannot use carName

Local variables can only be accessed within the function in which they are declared.
