[Solved] Is there any option to make it work? global+local varriable [closed]

Introduction

This question is about the use of global and local variables in programming. Global variables are variables that are accessible from any part of the program, while local variables are only accessible within the scope of the function they are declared in. The question is asking if there is any way to make a global and local variable work together.

Solution

Yes, you can use both global and local variables in your code. Global variables are declared outside of any function and can be accessed from anywhere in the program. Local variables are declared inside a function and can only be accessed within that function.

const players = [1, 2, 3, 4];

check();    
function check()    
{   
    // CAUTION : This is only a shallow copy and will work with value types
    // If you use on ref types, it will be pointing to the same objects.
    let innerArr = players.slice();
    innerArr.pop();    
    console.log(players); 
    console.log(innerArr);
    return innerArr;    
}

The answer to the question “Is there any option to make it work? global+local varriable” is yes. Global variables are variables that are declared outside of any function and are accessible from anywhere in the program. Local variables, on the other hand, are variables that are declared inside a function and are only accessible within that function. To make a global and local variable work together, you can use the global keyword. This keyword allows you to access the global variable from within the local function. For example:

// Global variable
var globalVar = "Hello World";

// Local function
function myFunction() {
  // Access the global variable
  var localVar = globalVar;
  // Do something with the local variable
  console.log(localVar);
}

// Call the local function
myFunction();

In the above example, the global variable is accessed from within the local function using the global keyword. This allows the local function to use the global variable and do something with it. This is a great way to make global and local variables work together.
