how to call variable in function in javascript

To call a variable inside a function in Javascript, you can pass the variable as an argument to the function or access it directly if the variable is within the same scope as the function.

Here is an example of how to call a variable in a function using an argument:

index.tsx
let x = 5;

function myFunction(param) {
  console.log(param);
}

myFunction(x); // Output: 5
94 chars
8 lines

In this example, the variable x is passed as an argument to the myFunction function, which then logs the value of the param parameter to the console.

Alternatively, if the variable is defined within the same scope as the function, you can access it directly:

index.tsx
let x = 5;

function myFunction() {
  console.log(x);
}

myFunction(); // Output: 5
84 chars
8 lines

In this example, the x variable is defined in the global scope and therefore accessible from within the myFunction function. The function logs the value of x to the console directly.
