Before printing the variable in the main function, we will call the fu() function to print the value in that function.But the variable had the local scope & it can't be accessed from the fu() function. So, the output will have one error that will imply that the variable is not ...
Scope has two benefits:Security : Variables that aren’t accessible from outside the specified scope won’t accidentally get changed later on. Naming : Allows you to use the same variable name in different scopes. You know this is helpful if you’ve used let i = 0 in ...

let student = new Student()Code language: JavaScript (javascript) This might look a little greek. But bear with me you will get the hang of this. The LHS is simply creating a variable student using let. On the RHS side, calling new on Student actually creates an Object that contains the...

A local variable is declared within a specific scope, such as inside a function, and its lifespan is limited to that scope. A global variable, on the other hand, is declared outside any function and can be accessed from anywhere in the program. ...
In the future, we might release updates to this functionality that abstract away some of the low-level coding that is required in this release for WebSockets applications.Bundling and MinificationBundling lets you combine individual JavaScript and CSS files into a bundle that can be treated like...
