Q - What will be the output of the below code and why

const number = 1
const result = (function (number) {
  delete number
  return number
})(10)
console.log(result)

Ans - The output of the above code is 10

Explanations

In this code, we are passing the value 10 as the input to the function. But again inside the function number is just a local primitive type of variable so delete will not make any changes to the number and the value 10 passed to the function will be returned from the function.
