Global Scope and Functions


In JavaScript, scope refers to the visibility of variables. Variables which are defined outside of a function block have Global scope. This means, they can be seen everywhere in your JavaScript code.

Variables which are used without the var keyword are automatically created in the global scope. This can create unintended consequences elsewhere in your code or when running a function again. You should always declare your variables with var.

Instructions

Using var, declare a global variable myGlobal outside of any function. Initialize it with a value of 10.

Inside function fun1, assign 5 to oopsGlobal without using the var keyword.
